Shift Kit-the ultimate in shifting technology


This kit will fit almost any stock, unmodified Chinese 2 Stroke bike engine and allow the user to shift gears using the bike's standard rear derailleur. This and our HD kits are what you see in the YouTube videos. Take a look at the parts list in our installation manual to see what we supply in this kit.

NOTE: This kit is not designed to work with the slant plug head engines. It is for 2 stroke engines with standard compression ratio straight plug head and is supplied with a standard front freewheel. If you have a slant head or raised compression engine, or a 66+cc engine you must use our HD kits or HD freewheel.

Note that this kit comes with typical mountain bike style crank arms and requires 9/16" pedals. If you have a one piece crank you will most likely need to purchase new pedals.
