It's a "Top Fuel" category drag racing motorcycle, pretty much scratchbuilt from styrene, steel, aluminium, resin and brass for all but the front fork/wheel assembly (which was modified from a Tamiya kit)... The bodywork is in styrene and the massive rear tire is in resin...and those pulleys were turned and hand carved in my Dremel tool...I since then purchased a Sherline lathe setup.

There is over 500 hours of work in there.
