"...Twin-Shift is unlike any Motorcycle Transmission Oil you have ever experienced. It is 'thee' Ultimate solution to slow, hard or missed shifts. Nothing smells like it, nothing looks like it and nothing even comes close to it's performance...  NOTHING!"
Twin Shift™ Synthetic Motorcycle Transmission Oil has been specially formulated to smoothen hard shifting making for faster and quicker shifting as well as reducing missed shifts & gear grinding.

Motorcycle transmission oils face substantial amounts of heat due to the mechanical operation of the transmission itself as well as the external heat absorption being created by the internal combustion process of the adjoining cylinders and pistons of the engine, not to mention the exhaust radiance emanating from the pipes nearby. The relatively small transmission gears and bearings receive a lot of excess stress forced onto precision gear faces during heavy usage which can result in accelerated heat conditions as well as the possibility of premature gear and bearing failure. Our
Twin-Shift High Performance Transmission Oil is specifically formulated for motorcycles and designed to improve lubrication, withstand heat, reduce gear and bearing heat as well as aiding in cooling engine temperatures through the wicking effect of the transmission being metallically connected to the engine. Reduce and even eliminate all gear related failures as while enjoying cooler operating temperatures from your transmission and engine instantly by "pouring in the performance" with Twin-Shift.

Each bottle of Twin-Shift™ is meticulously prepared and filled to the most stringent and accurate specifications, one at a time.

Twin Shift™ Synthetic Transmission Oil has been specially formulated to withstand ultra-severe punishment and extreme abuse of high performance street and competition applications.

Twin Shift™ is designed to provide superior   protection as well as survive against tremendous heat, high speed, extreme pressure and brutal torque shock-loading conditions. Adheres to metallic surfaces and will not drain off.

Twin Shift™ Synthetic gear oil based lubricant is thermally stable and engineered with all the necessary extreme cooling and beneficial high pressure additives included to make this the most potent lubrication package possible.

Twin-Shift™ incorporates the unique properties of enjoying the low viscosity and low resistance of a lighter gear oil while taking advantage of the lubrication adhesion and cooling benefits of a super sticky heavier gear oil.

"Twin-Shift™ works so good my Harley shifts like a Jap Bike now!!!"

"Twin-Shift™ works pretty darn good! So far I haven't missed a shift yet... and it really does shift as good as a Jap Bike!"
- Don Thomas (Wisconsin),
Harley Davidson

This is not an info-commercial or paid endorsement in any way.  Just installed Twin-Shift™ Motorcycle Transmission fluid in my custom bike's 6-speed Rev-Tech.  This stuff really does work.  My shift from 2nd to 3rd, and 5th to 6th was always a little touchy, and now it is much smoother.  Any of you that have had a Harley or any of the V-twin customs know how clunky and loud these transmissions can be.  Mine has quieted down considerably. Really like the quieter and smoother operation.
