Our Wild Boar Honda Navi 125cc Big Bore Piston Cylinder Kit is the first true light weight high compression piston and cylinder kit on the market.
The original Navi cylinder is a heavy cast iron cylinder designed more for economy then performance, our WILD BOAR kit reduces weight while giving a huge increase in power and torque even for the stock standard Navi.
This is the only major upgrade and mod to your Navi worth its weight in gold.
A big thank you to Andrew Davies from Leumeah NSW who’s Navi pictured here was the first big bore kit installed and tested in Australia.
Andy with years of motorcycle custom build experience spent time to thoroughly check all perimeters and to ensure the end product was to the highest standard ready for release.
Some of Andrews mods include a cam upgrade, clutch upgrade, aftermarket exhaust and bigger carburetor jets giving the bike much more bottom and top end speed transforming the bike.
