Fast50s "120cc Big Daddy" big bore kit that bores into your stock/ sleeved 100 cylinder. Make your bike a ripping "Sleeper" kit! (Still looks stock) It's the perfect addition for the Honda XR/CRF100! It's a 58mm 120cc but with the high compression dome we offer it will smoke other brands lower compression 120 kits!!
The compression ratio is 12:1 and it will still allow you use premium pump gas (We like to toss a lil race on top but not needed but runs better and cooler with race gas) and keep the reliability of your stock motor.
We also use the absolutely best quality Japanese rings available while many other brands use overseas poor quality rings that do not stand up to the abuse these bike commonly see.
