| Notes:
Suspension: For XC racing we offer narrower a arms. The stock front shocks have large bodies and large shafts which cause several problems - if you get them setup that they are plush - they will blow thru the travel and bottom on big hits. If you set them up so they dont bottom - they will ride harsh. For anyone serious about racing this quad you may want to check out aftermarket front shocks with smaller bodies and smaller shafts to give you good bottoming resistance while still maintaining a plush ride. The rear suspension linkage has a very high progression ratio which causes harshness toward the bottom of the stroke. Our Econo link with take some of the progression out and is an excellent link for MX racing due to the smaller tires and the different needs for MX - it is also an excellent link for the trail rider who just wants to lower the quad and soften it. For the series racer we offer the Pro Dual Link that give an even greater progression change then we can achieve with one link and also offers a better leverage ratio. This link however requires a shorter shock then stock.

We have been developing many new products for the YFZ
450R for both XC racing, MX racing and for the trail rider.
Foot pegs............................................................................................................................$99.95 These have the gripper teeth and are lowered 1/2 inch from stock but still offer excellent ground clearance. Suspension Rear Shock Conversion (Basic).........................................................................................$345.00 Includes: Revalve, Respring, and Econo Link. Rear Shock Conversion (Pro).............................................................................................$595.00 Includes: Revalve, Respring, Pro Dual Link, and a new high flow piston. HLS Basic front shocks.......................................................................................................$495.00 HLS Pro front shocks..........................................................................................................$895.00 XC A arms..........................................................................................................................$895.00 MX A arms.........................................................................................................................$895.00 170mm Econo Link.....................Part#09-009.................................................................$195.00 This is the front link - it is an excellent add on for the guy who wants to lower his quad and soften the rear shock with out spending a lot of money. Pro Dual Link.......................................................................................................................$375.00 This is a dual link and requires a different length shock but offers a better progression and leverage ratio curve vs. the Econo link. If we do your rear shock conversion - we modify your rear shock to accept this link. Please note: This link will not work with a stock rear shock that has not been modified by us. It will only be sold to existing customers who already have our shock conversion or as part of one of our shock conversions. Engine Piston Kit...............................................................................................................................$225.00 This is a custom made piston from Wiseco that gives good combustion action without having a high compression ratio - it runs much cooler then many of the high compression pistons available for the quad. It is the same style piston the the Yamaha's Factory riders were using in 2008 these riders included Pat Brown, Thomas Brown, Bill Ballance, Donnie Ockerman, and Brandon Sommers. This Piston is available in both 95 and 96mm. Camshafts..............................................................................................................................$425.00 These cams have the most average power of any cams I have tested. If you racing on the dyno only - dont buy these - they do not have as much peak power as a few others. Power Commander (basic)...................................................................................................$349.95 This comes with a custom modified fuel curve for racing. This comes programmed for your quad. I need to know what exhaust, with or without air box lid, what cams, what piston, what type of riding, what altitude, and what fuel you are running. Outer Sprocket Guard..........................................................................................................$49.95 You need to run some kind of chain guide with this to ensure that the chain does not come of to the inside. Dual Sprocket Guard...........................................................................................................$124.95 Please be aware that it is possible to get debris trapped in this setup causing severe engine damage!! Rotor Guard..........................................................................................................................$49.95 Note: The installation of this part is critical to the life of this part and it will wear out very fast under certain riding conditions. |
