old trials fanatic Posted January 20, 2020 Report Share Posted January 20, 2020 I'm in the process of restoring a Beta Rev 3 270 2006 and need to renew the chain and sprockets. So whats the best combination. No roadwork and sportsman / clubman rider. Cheers Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 21, 2020 Report Share Posted January 21, 2020 The trouble with the Rev 3 was the low first gear. I ran a 10 CS with stock rear sprocket. I always rode 2nd in almost every section. Quote Link to comment Share on other sites More sharing options...
