YES - I would race in the 250 Spec class
YES - I would likely buy/build one
YES - it would be in addition to my 160 - watch out - there are 2 of us now!
I think this is a great idea - and like my 160 - altho its proven to be the slowest bike in the MRA - or very close to it - I am hooked - love it and want to do more and Im starting my racing at 43 yr old - it could be a great low cost entry point - or a saving grace for those who can no longer - or want to - spend the big dollars!
