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?

 I recall them having kits for the enduro and motard bikes, but not sure about trials.

may have to call the importers
