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.
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.
Raises compression from stock 9.5:1 to 10.5:1 for more power and snappier 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. Fits the standard size stock bore.
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.
- 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.
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.
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.
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!
This kit of O.E. Suzuki O-rings replaces your leaky, weepy, and brittle O-rings that fit between your DR's oil cooler lines. You get 4 O-rings in this kit to replace both feed and return line O-rings.
If you're noticing oil leaking or creeping around your oil cooler, oil cooler lines, or engine, you may have one or more failed / failing oil cooler line O-rings. Replace them now before they completely fail and you run your motor dry of the precious oil it needs to operate properly.
- 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.
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.
The long awaited Wide Ratio Transmission from Nova Racing. Now you can have your trail gearing without giving up your highway gearing.
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 tables below show 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.
Stock | Gearing | Ratio |
1st | 12/29 | 2.42:1 |
2nd | 16/26 | 1.63:1 |
3rd | 21/26 | 1.24:1 |
4th | 21/21 | 1.00:1 |
5th | 23/19 | 0.83:1 |
The "A" gear set has an 8% wider gear ratio spread than stock.

The EXP disk is the magic ingredient behind the functionality and benefits of Rekluse auto clutches. About 10 years ago, Rekluse introduced an innovatively redesigned version of its revolutionary auto clutch technology with EXP 3.0. The years of racing, testing and development since have led to Rekluse’s most refined auto clutch experience yet; Introducing EXP 4.0.
No More Stalling:
Using principles of centrifugal force, EXP technology automatically engages and disengages the clutch based on engine RPM. With EXP, riders can start and stop without touching the clutch lever. EXP automatic clutch technology provides riders precision throttle control, maximum traction and confidence to maneuver any obstacle on the track, trail, or road.
Less Arm Fatigue:
You don’t have to clutch as often, which preserves your arm for longer rides.
Tunable to Fit Your Riding Style:
Each auto clutch is optimized for each bike model as it comes from the factory, and EXP 4.0 has been developed and tested in a wide range of late-model motorcycles. However, everybody rides differently, so they made sure EXP technology can be fine tuned. They offer different spring and wedge options so riders can further adjust their clutch’s performance. Some riders like the clutch to engage just above idle, while others like later engagement.
Clutch Lever Is Still Functional At All Times:
It is possible to fully override the auto functionality at any time. You can pull the lever in, build RPMs, pop the clutch out and raise the front tire just like normal.
Have More Fun:
You don’t have to worry about covering your clutch to prevent stalls all the time. You are free to relax and enjoy the ride, having one less thing to think about.
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.
In this kit you will get 4 factory replacement bolts to replace any broken or damaged clutch pressure plate bolts on your DR650.
It can be easy to over torque these bolts if not done properly. If one of these bolts is damaged on your DR650, we highly recommend replacing all 4 to prevent any future failures down the trail.
This is an extended version of the stock DR650 clutch release arm that is manufactured by Suzuki.
Upgrading to a longer clutch release arm will lighten the pull of the clutch lever through means of increased leverage. This means less fatigue, quicker clutch engagement, easier clutch modulation and longer rides.
The extended clutch arm will not offer a drastic change in clutch pull. If you're looking for a major change in clutch pull at the lever, we recommend getting a Magura hydraulic clutch kit.
This is one of the few plastic parts on the DR650 that can ruin your day if it breaks or fails on you. This gear helps drive the oil pump to circulate oil throughout your entire motor, without it, your motor will fail entirely. The idler gear is not known for being a common failure point in the DR650 motor but, it has failed riders in the past. Usually in the form of a broken gear or stripped teeth. Upon inspection, look for any kind of crack, chipped or missing teeth on the gear. It is not a complicated repair to swap an old gear for a new one, as the best time to replace it is when you've opened up the clutch side case cover for another repair i.e., (NSU screws or clutch hub bushing replacements). This is an O.E. Suzuki part.
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

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

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.
