Power Conversion Kits


Krause Racing / Sidewinder Products is the #1 source in the drive system industry for upsize and
downsize sprocket and chain conversion kits. Krause builds these matched, custom made, kits for
Street, Dirt, Race, and general Off Road applications. Sidewinder provides these power improving sets for
both Motorcycles and ATV's. All kits are complete with front sprocket, rear sprocket and matching chains.
Amazing power increases result by converting from stock, high-drag, power-robbing drive trains to
sidewinders' sleek, light, super tough conversion kits. A wide variety of conversions are available for
displacements from 60cc to 1000cc. In most cases a substantial reduction in weight results in much quicker
acceleration, less wear and tear on the transmission and clutch systems and a noticeable improvement
in the overall suspension due to the reduction of rotating mass.

Downsize Chain Conversion Kits
The Sidewinder Downsize chain pitch conversion systems are very popular with riders seeking
maximum power transfer, greater hole-shot potential and overall performance and handling
improvements. Drive system life and reliability is not compromised due to the selection of ultra-high
tensile strength sidewinder chains. Ti-Moly sprockets are provided in most kits.














Upsize Chain Conversion Kits

The Sidewinder upsize chain pitch conversion systems are the choice for riders building mega-powerful,
super-high horsepower hybrid projects or seeking to extend useful service life of the drive train well
beyond that available from the standard size system. In some instances the stock system (i.e. 2007 Honda
CRF150R), is grossly under designed and prone to failure and an upsize sidewinder kit is necessary to
insure reliability.
