Thanks for the info Rocketmannn.
Luckily these don't sell fast while I make up my mind. There is a standard 250 and the S model that are about the same price.
I kind of like the looks of the standard 250 better.
Are the engines physically different?
Can an exhaust from the S model be installed on the standard model?
I wouldn't mind doing a custom exhaust using a high quality aluminum or titanium stock take off of a larger bike grafted onto one of these bikes.
