In just a short time the CRF450X has grown immensely popular, and for good reason: Having won the grueling and world-renowned Baja 500 and Baja 1000 races multiple times, it has rightfully earned the title King of Baja.

“The Original” Power Pump w/ALJ is very easy to tune, meaning you can start getting quicker, more crisp throttle response almost instantly. This improves acceleration and power as a result, and of course makes you a better rider. This pump is great because it is essentially bolt-on power for the Honda CRF450X. There is no need to be an engineer or professional rider to get more power and throttle response out of your bike, parts like this can do the job nearly as well. The best part is that no drilling or modifications are required. Unlike some parts which are nearly impossible to install, and require you to rip apart your entire bike, “The Original” Pump from R&D Racing can be installed easily for instant improvement. At $100, it is also not a huge detriment to your wallet for the improvements it provides. “The Original” Pump fits most FCR-MX carburetors, including the Honda CRF450x. I would recommend this part to anyone interested in quick effective performance increases, to both track and trail riders.

This Steering Dampener, engineered by the Roc Stompa Company, is a superb way to decrease rider fatigue on your Honda CRF450X, by increasing steering ability as well as handling. A really good steering dampener is essential if you desire better control of your bike and want a small, easy to install part. The Roc Stompa Steering Dampener is especially useful because both the Original and Advanced versions feature a unique “Push-to-Cancel/Activate” dampening release feature. This means that when you need zero dampening in a hurry, for a short period of time, you can turn it off with a simple push of a knob. When you need the dampening features back, it is as easy as pulling the knob back up and the Roc Stompa will re-engage dampening at the previous settings.

But that’s not the only great part about this product. Not only is the Roc Stompa Steering Dampener very easy to use, and effective at dampening steering, but it is also extremely durable. Made out of tough 7075 Aerospace Grade billet aluminum, this product is going to stand up to everything you can throw at it. It can even handle the elements as well, since it is fully anodized for maximum surface protection and corrosion resistance. While being so tough, the dampener also manages to remain lightweight, by having a compact form factor and extremely durable lightweight materials. The Roc Stompa is also proven to be strong, since it is FEA (Finite Element Analysis) tested. This means that stress points were located in designing it to determine the strongest possible construction, making this one part that’s likely never to break on you.

The Roc Stompa Steering Dampener stands out from other dampeners, not only in its strong lightweight construction, but also in its unique progressive dampening control. Most dampeners on the market require you to take your eyes off the track to adjust dampening, which is both dangerous, and ineffective, not to mention the fact that it slows you down. The Roc Stompa can produce dampening anywhere along the dial with just a simple adjustment, meaning you can keep your speed up and eyes on the road, even when adjusting dampening, both very critical with a beast of a bike like the CRF450X.

The Roc Stompa Steering Dampener comes in two varieties, the Original in red to match your Honda and the Advanced in yellow. While the Advanced was designed with desert racing and motocross in mind, the Original was designed for most trail riders and amateurs, and offers excellent value for money. Both feature the same technologies, but the Advanced adds more durability, with a steel arm and pin. Also included in the Advanced is zero dampening on return to center, meaning that the bike will get on track even faster. The Roc Stompa has very easy mounting kits which fit most bike types and models. There are both above and under bar kits. Like the rest of the product, the kits are constructed with durable 7075 Aerospace Grade billet Aluminum. The Roc Stompa can be purchased from RocStompa.com.

Loose fuel screws which plague many riders, especially those of the Honda CRF450X, are a thing of the past with the Flex-Jet Fuel Screw. The product has the ability to hold its setting no matter how much vibration , something many riders will be happy to hear. This product is excellent for both track and trail riding, and is almost essential for those who are sick of burning their fingers, or having any sort of hassle with their bike’s fuel screw. This product fits most bikes, including the Honda CRF450X. Installation is a breeze and the price is worth it, considering the amount of hassle it saves. The R&D Flex Jet Remote Fuel Screw can be found at R&D Racing

Another option to look at for slip-on exhausts, is the FMF Factory 4.1 SL with Titanium or Stainless Steel Midpipe. FMF says that “anyone can make a bolt on system, but not anyone can give you the innovations and patent pending technologies FMF offers”. The Factory 4.1 SL was created to boost mid torque, broaden the powerband, and increase the over-rev. It features the exclusive Chamber Core technology, is said to improve handling by centralizing mass, and unlike the Yoshimura is made from premium quality American materials. The FMF Factory 4.1 SL can be customized with performance tuning inserts as well as a spark arrestor module. This great slip-on may not be as proven as a full exhaust system, but the wealth of technologies, innovations, and research that have gone into its creation show that it is not just another bolt-on system. It is priced comparably at $425 to $500.

If you desire a guaranteed performance increase, going with a full exhaust system from Yoshimura R&D is likely the best bet. Yoshimura’s RS-2 Full Exhaust system comes in three varieties; Titanium/Carbon, Titanium/Titanium, and Stainless/Aluminum. The Stainless/Aluminum option is priced significantly cheaper at $595 compared to $895 and $845 respectively, but this obviously comes at the price of being heavier, and not quite as durable. Regardless of the trim option, the RS-2 Exhaust system from Yoshimura outperforms the stock system almost across the board, clearly breaking away in the 8,000-11,000 RPM range. If you desire tested and proven mid to high range power this is definitely the system to buy. The RS-2 Pro_Series features a removable 99db USFS approved low-volume insert, a Titanium or Stainless header and mid-pipe, and three variations of sleeve options.

The F2 racing Fast-Cap is a product developed by the great minds at F2 racing, which is designed to keep the flow of the fuel constant. When testing the world’s fastest bike, researchers at F2 noticed that it would start to “run lean” at very high speeds, as the stock float bowl cap allows fuel to flow away from the center, where the jets are fed. With this $30 cap, performance is improved dramatically, as the fuel flow is more direct. At sustained high speeds, the problem of the bike “running lean” or not getting enough fuel, is eliminated and a far more consistent top speed is achieved. The Fast-Cap is a relatively small after market part that fits on to an existing carburetor. F2 claims that in nearly any kind of racing, the top speed is not only more consistent than with the stock, but also higher. On the world’s fastest dirt bike they were able to obtain another 800 RPM and an extra 6 miles per hour in the top speed! And this was with no other modifications, just the simple $30 F2 Fast-cap.

This product has been proven to be beneficial not only to pure racers, but also for trail riders. The cap is said to achieve a far more constant fuel flow, which means a far crisper throttle response, exactly what many trail riders are looking for in a product. Reviewers have claimed that they saw a definite increase in smoothness over the stock setup, especially in uphill climbs and large jumps. The Fast Cap is also excellent at improving crispness across obstacles and turns, simply because it is better at controlling the fuel flow than the stock parts. This smoothness in control and throttle response means that many people will become more confident riders, never having to worry about stutters or slight losses in power, at the top of a hill or jump, where it is needed most. The Fast-Cap fits all FCR and Kehien 2-stroke carburetors, comes in red or orange, and is very comparably priced at $30.

Another new product on the market is the Power Bowl, a product recently released by R&D Racing. This billet aluminum float bowl not only has more fuel capacity for the times your carb burbles over the breaking bumbs or choppy whoop sections, it also is tunable and has a more powerful accelerator pump. You can tune the leak jet to achieve better timing for the accelerator pump which in turn cleans up your pilot circuit for a crisp throttle response. Owner and designer Dean Dickerson explains his product like this: “With the advent of high performance 4 stroke engines, carburetor hesitation is a far too common occurrence. Temporary lack of fuel supply, caused by air pockets finding their way to jet passages, also cavitation in the accelerator pump, can quickly deflate a rider’s confidence in his machine. The R&D Power Bowl is a sure fix for these problems. During hard landings and high speed impacts, excessive fuel splash currently exists. Splashing coupled with excessive clearance around the production fuel baffle, allows air pockets to reach the main and pilot jet, resulting in an extreme lean condition, commonly known as bogging.

“This new carburetor bowl, designed with our new Zero Tolerance Jet Chamber, minimizes existing clearances eliminating the possibility of fuel evacuation around the main and pilot jet area. (no bog).”

Most of that reads like Chinese to a mechanically retarded person like me, but Dean insists that his product is the answer until all production bikes have electronic fuel injection figured out.

A BETTER SOLUTION!!!
R&D’s Power Bowl, the cure for unpredictable carburetor performance, common in todays motocross bikes.

MIKE ALESSI #800
My bike runs cleaner around the whole track …no bog, no hesitation any where, it also quicker off the start.
I used the Power Bowl on my RED BULL Factory KTM bike for the entire 2007 East Coast Supercross season,
thanks R&D, for a great product.

PROBLEM SOLVER
With the advent of high performance 4 stroke engines, carburetor hesitation is a far too common occurrence.
Temporary lack of fuel supply, caused by air pockets finding their way to jet passages, also cavitation in the
accelerator pump, can quickly deflate a riders confidence in his machine. The solution? ”R&D’S POWER BOWL”
the complete answer to a real problem.

JET CHAMBER
During hard landings and square edge impacts, the production Keihin carburetor design, allows fuel to splash
away for the main and pilot jet chamber. Jets temporarily exposed to air pockets, will cause any engine to misfire,
commonly knows as “BOG”

The R&D Power Bowl, is designed with the new ”ZERO TOLERANCE JET CHAMBER”.
This new design redirects fuel during hard impacts, creating maximum fuel exposure during extreme conditions,
eliminating the possibility of fuel evacuation around the main and pilot jet area, completely eliminating the possibility
of misfiring.

ACCELERATOR PUMP
R&D’s ANTI-CAVITATION accelerator pump is state of the art, designed with two separate fuel ports. Port one,
is positioned at the HIGHEST point in the A/P chamber, allowing entrapped air to escape through the leak jet orifice.
Port two, is isolated LOW in the fuel sump, assuring ‘FUEL ONLY’ into the venturi, unique to R&D’s A/P design, and is
the key to our superior performance.

PUSHING THE ENVELOPE
With all the new advances in the ”R&D POWER BOWL”, we also included an externally adjustable leak jet for fine tuning,
it’s just a quick and easy hand adjustment. The ball check valve has also been redesigned, relocated at the bottom
of the pump cover for a more consistant fuel supply. The stock steel ball in the check valve has also been replaced
with a nylon type for an improve responce time during hard landing and hard impacts.

Ty’s Hot Start Carb Nut fits the 03-04 YZ/WR 250F/450F, as well as the CRFs, KX-Fs, RM-Zs, and KTM ‘RFS’ bikes, and replaces the stock plastic unit with a red anodized, billet aluminum unit. If Ty designs a replacement part, he doesn’t just solve the one problem which initiates his quest for a better part. He will try to improve the part in any way he can. In the case of the Hot Start Carb Nut, that’s exactly what he did. The stock plastic nut can crack and self-destruct without even touching it. And, it was very difficult to get a wrench on the hex given the tight confines of that area of the carb. Ty created a much smaller hex - 10mm - which takes the smaller wrench. Now, you can actually get a wrench on it. That’s what I’m talkin’ about!
