Wiseco 96mm piston with rings, wrist pin, circlips, head gasket, and base gasket. Requires your cylinder to be bored to fit the larger piston.

Special order item. Allow 10 extra days for delivery.

The 790cc Big Bore Kit includes a custom made, forged 9.5:1 piston with rings, wrist pin and circlips. A custom made multi-layer steel head gasket, OEM metal base gasket, tensioner gasket, and cam bolt lock plate and a ProCycle specific big bore cylinder sleeve. We recommend adding a KRAMM-Lox tool for easier piston circlip instalation.

Cylinders with 790 sleeves installed are usually in stock, but we must have your original cylinder as a 'core'. These cores allow us to keep up this program and it is nothing more than an exchange - we give you ours, you give us yours.

Raises compression from stock 9.5:1 to 10.5:1 for more power, torque and snappier engine response. The high quality forged piston from JE is almost a full ounce lighter than the stock cast piston. This makes for less vibration and a smoother running motor. Includes rings, pin, clips, and top end gasket set with valve stem seals and metal base gasket. Fits the standard size stock bore.

The Complete Top End Performance Kit includes:

10.5:1 compression JE piston with rings, wrist pin and circlips (the actual measured stock compression is only 8.7:1).
Stage 2 Web Cams high performance camshaft for more power (reground from brand new OEM Suzuki camshafts).
Top end gasket set with metal base gasket.

We strongly recommend checking valve to piston clearance when installing a non-standard camshaft.

This is the little rubber plug on the right hand side of the cylinder head. Replace this plug to avoid having an oil leak after disassembling your top top end.

Solid reliability and easy installation. This manual tensioner is a good upgrade for any modified motor, especially if it is ridden hard.

A new gasket is included.
 

A Suzuki OEM gasket for the Cam Chain Tensioner. You are going to need it if you work on your starter motor. It is not a good idea to re-use this gasket. If it blows out, it will dump a large amount of oil onto your right foot.
 

Your automatic cam chain tensioner is spring loaded. This can make it difficult to install as it wants to extend before you have it bolted into place. This handy tool will back off the cam chain tensioner mechanism and hold it for you. No more awkward 3-handed contortions are required to get the tensioner installed.
 

An upgrade over stock, these hard-welded premium rockers are highly recommended when upgrading your camshaft.

Kit includes all new OE adjuster screws and lock nuts.

Please see required core information below.

• Our own #190 cam profile offers more lift to give better low-end and mid-range punch and more duration to keep the motor pulling hard in the upper RPMs.
• Our performance cams are reground from OEM camshafts - no core charge or return required.
• We recommend a high compression or big bore piston to get the most out of your performance camshaft.

We strongly recommend checking valve to piston clearance when installing a non-standard camshaft.

Cylinder head upgrade. Features CNC machined port shapes, larger high performance valve seats and custom made valves. Valve sizes are increased from the tiny stock 33mm intake & 28mm exhaust to 36mm intake & 32mm exhaust. This is not a radical modification. These bigger valves bring the valve sizes up to what would normally be found on other brands of 650 singles.

Big Valve Heads are sold only on an exchange basis. We need your stock head for the next batch of modified heads.

 We strongly recommend checking valve to piston clearance when installing oversized valves.

K&L® shims exceed the maximum of the Apparent Rockwell Hardness "C" scale. Shims average 47.0 compared to the 46.0 maximum.

These kits fit multiple brands and models, please verify correct size for your model before purchase.

Ride in warm temperatures a lot? Worried about your motor oil just getting too hot? The Trail Tech Universal Fan Kit mounts up to the backside of the DR's oil cooler to draw cool air across it and keep those oil temps down. An electronic temperature sensor mounts to the fan, no need to cut any fluid lines, and automatically turns the fan on when needed to keep the temperature in the optimum range.

The activation sensor can be set wherever you like to keep the temperature right where you want it. Backlit for easy viewing anytime it also includes a volt meter.

Kit Contents

• 4 inch SPAL fan
• TTV Temp Meter
• Temperature Sensor
• Complete Wire Harness

What would you do if your oil cooler was damaged way out in the bush? We have a simple solution. This kit allows you to bypass the oil cooler and both oil lines and insure that the top end continues to get the oil it needs to stay healthy. Simply remove the stock oil lines from the motor and attach one end of the bypass at the head and the other end at the engine side case. Be sure to leave the original o-rings in place.

Small, light weight and easy to carry. You may never need it but if you do it will save you a lot of walking!

• Protect your DR650 from overheating.
• Inline temp block kit works with Trail Tech computers Striker, Vapor, Voyager, Voyager Pro, and all TTO temp meters. 
• Installs between the oil cooler and top oil supply line, giving a cooled oil temp reading.
• Includes 3 new o-rings, and 2 longer bolts, as well as the Trail Tech m6x1.0 temp prob.

This is a genuine Suzuki part. We recommend installing a countershaft seal retainer to prevent the countershaft seal from popping out while riding.

OEM Suzuki seal retainer for the DR650. Simple insurance against your countershaft seal popping out of its bore.

This is not a common problem but for those folks who have had the seal come out it has proven to be quite difficult to get it to stay in place. This steel retainer eliminates any possibility of the seal coming out and ruining your day by coating your rear tire with oil.

The Neutral Sending Unit "NSU" on the DR650 can be a problem. The factory screws tend to loosen over time. You really would not want them to get loose in your motor! The permanent solution is to safety wire them. We looked high and low and finally found pre-drilled screws in the correct length and thread pitch. Here we offer a complete kit to take care of those pesky screws.

If you don't do this, you don't have a screw loose, you have TWO screws loose!

Kit Contents

• 2 drilled stainless steel screws
• Plenty of safety wire
• Wire twisting tool
• New lock tab for the clutch hub
• New clutch cover gasket

The starter bushing in the DR650 leads a tough life. Exhaust heat and minimal lube from the factory take their toll. Warp 9 has a high quality solution - a billet starter cover with a sealed ball bearing.

• CNC machined starter endcap
• Black anodized for good looks
• High Speed Abec 3 double sealed roller bearing installed
• Reduced amperage needed to start bike
• Brushes will have extended life

New starters that are manufactured to meet or exceed OEM specifications. Pull out your old starter, put in this new one and go riding. These units are built to provide a longer life than the OEM unit with these features:

• The armature is insulated for rust and corrosion protection
• Rubber seals on the top and bottom of the unit ensure a dry operation
• 90/10 copper bushings
• Extended shaft replaces long or short shaft OEM starters

This 3rd gear set is made for us by Nova Racing Transmissions in England to replace the fragile stock third gear set. These folks build complete transmissions for World Superbike teams among others, so we believe them to be highly qualified to build this set of replacement gears.

These gears are made from a high quality special alloy steel and then heat treated and superfinished. The mainshaft drive gear and the countershaft driven gear are sold only as a set.

The long awaited Wide Ratio Transmission from Nova Racing. Now you can have your trail gearing without giving up your highway gearing. The "A" gear set has an 8% wider gear ratio spread than stock. The "B" gear set gives you a 13% wider gear ratio spread by making first gear even lower. Both sets are lower than stock in 1st and 2nd gear and taller than stock on 3rd thru 5th gears. Not only will Nova give you better gear ratios but the high quality components will shift smoother and engage more solidly. The table below shows each gear ratio and the original OEM ratios for comparison.

To help put the ratio changes into perspective switching from the OEM 15T to a 14T sprocket lowers the gearing by 7.1% in all gears. Switching from a 15T to a 16T raises the gearing by 6.6% in all gears.

Barnett high performance clutch set. Includes 8 Kevlar friction plates, the 7 'loose' steel drive plates, stronger springs and a high quality clutch cover gasket.
 

Top quality friction plates, steel plates and heavy duty springs from Dunlop. Don't forget to use a new clutch cover gasket.
 

Complete set of friction plates, HD springs and steel separator plates prevent premature driven plate wear, oil muddying and loss of stack height. Built with swaged aluminum carriers that spread the load on the clutch basket and prevent clutch basket "dogging". Anti-swell, alloy impregnated heavy-duty facings for smooth clutch action. Allows modulation, unlike paper clutches which tend to snatch. Don't forget to add a fresh gasket.

This kit includes one OEM drive plate retaining wire & one OEM inner steel drive plate. 

If you've ever changed the clutch on a DR650 you will be familiar with the extra steel plate at the bottom of the stack that is locked in place by a very thin metal wire. 

Generally, when you do a clutch replacement on the DR650, you do not need to remove or replace these items. If you do need to (or if you have already) you will come to realize this wire is not very strong and is prone to breaking if not treated with care during the removal / installation process.

Barnett clutch springs are made from the finest materials available.

Heavy Duty Barnett clutch springs are pre-set, shot-peened, and heat treated for performance and durability.
 

Dragging clutch? Hard to find neutral? Maybe it feels like it doesn't fully release. These problems can be caused by worn thrust washers in the clutch assembly. Most DR650s show wear on these items. Kit includes #1, #2 and #3 in the diagram.
 

Complete set of engine gaskets and oil seals. Includes the addition of a factory Suzuki metal base gasket. A metal base gasket is essential because paper base gaskets will fail in the DR650.

Kit Includes:

• Factory Suzuki metal base gasket
• Head gasket
• Clutch cover gasket
• Cam chain tensioner gasket
• Mag cover gasket
• Exhaust gasket
• All oil seals
• All o-rings

Top end gasket set with the addition of a factory Suzuki metal base gasket. A metal base gasket is essential because paper base gaskets will fail in the DR650.

High quality clutch cover gasket. If you are servicing your clutch, a new gasket will prevent oil leaks.
 

High quality left side case gasket. If you are servicing your stator or starter clutch gears, a new gasket will prevent oil leaks.
 

Billet plugs for your left side case. Includes both the timing mark plug and the crankshaft access plug.
 

Fresh o-rings to ensure your DR650 stays oil-tight and leak free. Includes one of each: oil filter o-ring, filter cover o-ring and filler cap o-ring
 

A pair of factory OEM o-rings for the valve covers. Your valve cover o-rings live in one of the hottest parts of the engine and have a pretty short life. Replace them on your next valve adjustment to prevent oil leaks.
 

This is all you need to not only change your oil, but protect your motor as well. We include a magnetic drain plug, to help catch stray metal pieces, a 10-pack of oil filters, and new O-Rings to replace any you have that may be leaking or worn.

The PSR Oil Filler Caps are CNC machined from high quality aluminum and come with an E-clip that is already safety wired to a mounting tab. The wire is covered with silicone tubing that will not melt or discolor. Available in silver, black and gun metal.

New from the folks at Warp 9, a CNC billet machined Oil Filler Cap. Available in Blue or Black and it includes a new O-ring! To make removal as easy as possible, the center tab takes a 12mm wrench perfectly, or a 1/4" ratchet drive in the center! On each end of the center tab is a drilled hole should you find it necessary to safety wire your filler cap in place.
 

Superior Filtration:

This should be the last oil filter you will ever buy. Made from laser cut, medical grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area than other filters in many cases. Most good paper filters will pass particles in the 90 to 95 micron range, and some tested, as much as 300 microns. Sand is about 125 microns and a white blood cell approximately 25 microns. Scott's stainless filter catches items down to 35 microns "absolute". The pleat seam is welded, able to withstand up to 600 degrees, not glued, like paper filters.

• Cleanable and reusable filter
• 35 micron stainless steel mesh
• Stainless check ball and stainless spring
• CNC aluminum caps front and rear

Providing unbeatable performance and exceptional value, Hi-Flo is the best-selling brand of aftermarket filters for motorcycles, scooters, and ATVs worldwide. The filters are also supplied to original equipment manufacturers as well as private label brands.

You pay $3.70 per filter with our value 10-pack!

It is a good practice to replace your sealing washer with every oil change. These 10 piece kits are made up of 5 Copper washers and 5 Aluminum washers. The manufacturer recently decided to make half of the kit Copper washers as that is the material of choice for many OEM manufactures. This gives you the opportunity to decide which you prefer, but either will work great at creating a leak-free seal between the case and the drain plug.

Extra protection for your motor. A strong magnet at the end of the plug picks up metallic flakes in your oil.

E3 Resistor Spark Plugs

• Unique electrode shape maximizes the power created by the spark plug – Diamond Fire technology
• Electrode is a combination of performance and technology that results in an improved flame kernel shape
• This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
• The result is more complete combustion and an improvement in engine performance
• A truly premium performance plug
• Sold individually, unless otherwise stated.

Iridium spark plugs are made with premium quality materials.

Iridium plugs last longer than standard ones, meaning you won't have to replace them as often.

• The ultimate in the evolution of spark plug technology and performance from an industry leader
• The iridium electrode is 25% smaller than a platinum electrode, and it's just 1/4 the size of a conventional nickel electrode
• Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
• Metal shell plating has enhanced anti corrosion qualities
