250 ain't man enough.......
So, 250's are boring. Someone said going from an RS125- R6 is the way to go.
Hmm, depends if you wanna do it that way doesn't it?
I remember the Honda CBR 250 and ZXR 250R,Yamaha FZR 250,FAZER 250 and Suzuki GSXR 250, four cylinder F/S,revving to 17,000 rpm from 80's/90's JAPAN.
The Honda had gear driven cam's,tiny jewel like valves and spark plugs,alloy frame and was immaculate in construction.
Boring they weren't and even though they'd only top 112mph 45 bhp they looked the biz.
However,i must admit maybe Yamaha should build the YZF R4 as in 400cc 65bhp,136mph and looking like the above, why not, apart from price of course,as thy'd probably ask £6-7,000 for it,no doubt.
