can someone confirm for me that a 125 stroke engine from a 2007 gilera runner will fit in a 2011 gilera runner 50cc?
A 125 what engine, 2t /4t? and no it won't fit in a 50cc frame without a load of bodeging and grinding. Buy a 125 to start with.
4 stroke sorry, and nah not too much work only fitting it and ive got someone to do it for 50quid if i cant be bothered but ill see what others say as ive known a few people with 50 runners with 172/210 engines in which were 125s
