TB Parts 186cc Big Bore Performance Kit - TBW9150
This is a brand new 186cc Big Bore Performance Kit from TBparts who is the USA leader in performance big bore kits for the Honda 50cc, 70cc, 100cc, and 110cc models.
This is the largest bore kit on the market and is as big as you can go without having to bore your cases.
It includes the following parts:
- An all aluminum ceramic plated 64mm cylinder. This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker).
- High quality 64mm piston kit that include rings, wrist pin and clips.
- The pistons are CNC machined to exacting tolerances.
- Top end gasket kit
These are high quality parts and definitely will dramatically increase the power and fun factor on your Grom!
IMPORTANT NOTE: Must be used with an aftermarket fuel controller to prevent a lean condition and damage to your engine
