My daughter bought a new Venox 250 in 2010. She had been in the market for a new motorcycle after having a old Yamaha Virago 250 as a first motorcycle.
All bikes she looked at were taller than she wanted and the Kymco dealer was the only willing to offer a solution.
So they fitted a 160/60-15 rear tyre lowering the bike enough and giving the bike better acceleration and top speed.
Now I have a Venox 250 I thought of doing the same but the 160/60-15 tyres are too expensive. I have fitted a 43 tooth sprocket for performance and lowering the rear with 10.5 inch for styling reasons. this lowers the rears about 2.5-3 inches.
Care needs to be taken to ensure the lean angle is still enough, I used 15mm longer spacer tubes to raise the front slightly.
