rick rexroat Posted November 23, 2018 Report Share Posted November 23, 2018 So I purchased a Beta Rev 50 for my grandson, he was on a TY80. Although the Beta is lacking in power the brakes, weight and suspension more than make up for it. I was wanting to big bore it just to help out the low end. Has anybody found a kit or a solution to the lack of low end on these bikes? Quote Link to comment Share on other sites More sharing options...
