TB 130cc Big Bore Kit - TTR110

Bolt on big power with the new 130cc Bore Kit for TTR110s (All Years)

• Lightweight high compression domed piston with rings, pin, & clips (91+ Octane Pump Fuel Safe!)
• 55.5mm, this is the biggest bore kit you can install without needing machining to the cases (case boring). These are high quality parts and definitely will dramatically increase the power and fun factor on your bike!

There are no installation instructions, but if you can replace your piston, you can install this kit as the parts are installed in the same manner as the OEM parts.  However, it's highly recommended that a professional install this kit and make sure its tuned properly to prevent a lean condition and damage to your engine.
