I've not seen this one before but I have seen similar.
What puts me off is no reverse! Unless you go for some fancy pants custom gearbox you wont have a reverse gear, cos most bikes dont have one.
If you intended to use it on the road, there would be a few problems...
The hydraulic handbrake. Does it still have the mechanical brake too? To pass an MOT there must be a mechanical means of holding the handbrake on, like the ratchet on the handbrake lever. Things like 'gas tap' type lock off valves aren't acceptable.
If you put a ratchet on a hydraulic handbrake used for drifting it becomes a pain in the @rse to use.
Also, to avoid a Q registration you would need to use a certain amount of parts from the original car. Its safe to assume the engine, transmission and suspension are not original, using the type approval points system means it would automatically be given a Q plate. Even if you got that past them, they would no doubt pick up on the facelift front end on a pre facelift shell?
As a toy, if done properly its probably great but as a roadcar its gonna be a nightmare. Besides, as Will pointed out its a repost, which probably means its been on ebay before. Which means someone else has bought it, realised whats involved in putting it on the road and is now reselling it!
