Moderator Cynic Posted August 4, 2017 Moderator Share Posted August 4, 2017 Then with respect your not looking in the right place. With the words "yamaha xvs125 bigbore" google spat pages of info at me including pictures and links to the virago forum for some specific threads. You will absolotely need new barrels. Personally i think its an awful lot of cash for not a lot. Link to comment Share on other sites More sharing options...
fras1 Posted August 22, 2017 Share Posted August 22, 2017 Cristian, you'd probably save yourself a lot of time ,grief and money by just trading up and getting yourself an XVS250. I have one of these,and they are very good bikes. Don't know if you're in the US or the UK, but if you're in the US the bikes were available, I believe, with mag wheels which means you can run on tubeless . Still easy to get parts (in the UK anyway) - I just bought a new set of coils for mine. good luck whatever you decide Link to comment Share on other sites More sharing options...
Tommy xs Posted August 22, 2017 Share Posted August 22, 2017 Well if a daggie is your thing go for the 650. I know we all get attached to a certain bike but if it ain't got the power you need, better to upgrade as others have said. Link to comment Share on other sites More sharing options...
