R1 seat

[misterjayb1]

I assume you just mean the tail end as most "streetfighters" are without the fairing...  Maybe look to some shorter dog bone linkages to raise the rear for starters?.. Cheap enough and will alter stance and handling.. Easily removed and dont have to be permanent fixture. An aftermarket undertray and tail tidy also if you want to go a step further.. I'd be interested to see a quick release sportbike seat unit that doesnt require modification of the subframe..
