The frame isnt plated up, its been completly re-structured. The machined sections welded on and blended in under the front of the seat are the only subframe as the carbon seat is self supporting.

The central spars have been increased in size and are braced between them, it weighs 117kg wet and makes over 110bhp (at the rear wheel on a Dynapro and Dynojet dyno) what is the weight/power of your average NSR250?

I seem to remember the fox craft RGV500 at the Llandow track day making the 250's look like they had a reverse gear down the main straight and out of the corners! But like you said not worth the difference...............
