GY6 High Performance Koso Racing Transmission Package
If you purchase one of our engines we will install this transmission in your engine if you also purchase this product.
Get more torque and power to your wheels with the BDX High Performance Racing Transmission
The difference between a sluggish and slow buggy, ATV, scooter or UTV can be found in the transmission. We have seen some great buggies, such as the Dongfang 170cc go kart. But it is slow and sluggish because of its stock transmission. This can easily be remedied with our GY6 High Performance Racing Transmission package which includes
Four sets of Koso roller weights for you to optimize top end speed and low end torque of your vehicle (9g, 10g, 12g and 14 grams). If you purchase an engine one set is included inside of your engine.
This Koso high stall clutch unit engages at higher RPM with more force than the standard clutch. This helps during steep hill climbing, towing, or when forcing the front end up over large obstacles. This unit provides a better launch from a stand still as well.
The Koso 115mm Performance Variator Included
2 piece variator
12g roller weights
Improved acceleration and hill climbing
Improved usage of powerband
Keeps you within good power range at all speeds
Revised Roller Ramp Angles
Teflon Coated Ramps
The Koso 115mm and variators are designed with steeper roller ramp angles for an improved acceleration and hill climbing. The revised roller ramp angles delay the CVT up-shifting process until the engine's powerband is reached - starting at approximately 6500rpm.
This keeps you well within good power range even at low speeds, and optimizes acceleration RPM when flooring it.
1500 RPM Clutch Spring
Extended Low Gear
Reduces Belt Slippage
Doesn't reduce top speed
For GY6 engine
This stiffer transmission spring keeps your CVT transmission in lower gear longer, allowing higher RPMs at lower speeds. This extends the amount of throttle you can apply at low speeds, and ultimately allowing more low-gear power to the wheels before the transmission begins to shift to higher gearing ratios. This is important for buggies where low-end power is what we're after.
