• Designed for riders who want more horsepower and the powerband higher in the RPM range • Requires high-lift valve springs (Fueling Beehive Endurance or High Load valve springs recommended) • Higher compression also recommended, along with performance...

• Designed for all-purpose 2-stroke riding • Durability, longevity and increased horsepower • Dedicated forging design for strength-to-weight optimization • Extra lightening operations for enhanced throttle response • Engineered, forged, and machined in...

• Conversion camshafts are a hybrid, with early '99-'06 inner cam journals and late '07-'17 outer cam journals • Update old mechanical-style cams and tensioners to new-style hydraulic tensioner system • 525 Cam: • Designed to increase torque band width...

• Comes complete with crankpin, big-end bearing, small-end bearing, and washers • Easy to install - Honda TRX250R FourTrax (1986); Honda ATC 250 R (1986, 1985)

• Carburetor and or throttle body work required along with a performance exhaust and intake system • Maintains low end performance with eye-blurring mid and top end power • High-performance valve springs, pushrods and lifters required • 2500-6900+ RPM...

• Aggressive pulling power with a “nasty” sound, the Reaper 521 grind will shine in 114” and larger cubic inch engines with added compression ratio • Ported cylinder heads are not required, but will complement the cam and add even more pulling power...

• Aggressive camshaft requiring high lift and higher load valvesprings, performance pushrods and lifters • High flow air cleaner and triple stepped exhaust pipe highly recommended • Heavy duty pushrods are highly recommended • RPM range 2,850 - 6,250 -...

• A four-gear set is required for gear-driven cams that do not come with secondary cam gears; includes two secondary cam gears, outer cam drive gear, outer pinion drive gear and mounting hardware • Due to the inherent characteristics of gear drives, you...
