Buell X1 Ligntning from 2000.
Harly Davidson 1200cc Twin engine, bumped to 100bhp and stuck in a sportsbike chasis.
This one has UK gearing so is doing 3000rpm @ 30mph in 1st gear and 4000rpm @ 100mph in 5th.
Forcewind filter and V&M system fitted.
Bike handles very well indeed and feels well planted on all road surfaces.
