DR650

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.

Our logo on a 20oz double wall 18/8 stainless steel thermal tumbler with copper vacuum insulation, threaded snap-fit lid, and powder coated finish.

The copper plating on the inner wall is an extra defense against temperature transfer.  Heat escapes much slower so your hot coffee stays hot even in a snow storm, and heat enters much slower so your ice water doesn't melt even under a blistering summer sun.

We have personally tested this bottle with 160° water placed on it's side for 7 hours, mimicking being in a saddle bag with coffee from the morning campsite and found that the bottle did not leak when the lid was properly secured and the water only dropped to 113° and the end of our test.

Pair it with the OBR bottle wrap for even better value and have a holder on your luggage for your new bottle for ease of access and security.

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.

A set of four high quality valve stem seals.

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.

• 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.

• Powerful magnet traps abrasive metal particles down to 1 micron. OEM oil filters only filter particles down to 90 microns, leaving behind the most harmful particles to circulate through your engine.

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

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.
