Fast50s "95cc Big Daddy" big bore kit is an AMERICAN MADE kit that bores straight into your stock 80 cylinder, we repeat you bore your stock cylinder to accept this piston kit.
This kit alone makes your mild mannered 80 into a arm jerking wheelie machine. Did we mention the best part is it's American Made and it makes your bike an awesome "Sleeper" kit!
Sleeper means (Still looks stock) It's the perfect addition for the Honda XR80 / CRF80!So basically now you have a stump removal machine in your 80.

It's a full (51mm) @ 92cc but with the high compression dome (12.25:1 ratio) we offer it will smoke other brands lower compression 95cc kits so that's why not call it what it beats!!
A compression ratio of 12.25:1 still allows you use premium pump gas & to keep it reliable like the stock Motor. (Sure toss a Lil race gas on top, not needed but runs even better)
We also use the absolute best quality Japanese piston rings available, while other brands poor quality "overseas" rings. We / You want something that will stand up to the abuse these bikes commonly see ripping around the countryside, woods and backyards of the world.

Our kit is made from the best components available on the market, our 92/95cc big bore kit will amaze & delight you.
It's a true race ready hot rod "bore in" sleeper kit!
