GP 450 Super Singles
Has anyone ever rode one of these converted 450 MX bikes? They look pretty interesting for a fun track bike. From the research that I've been doing, it looks like one can be had for about $4,000 on top of the price of the dirtbike.
I know it's not the cheapest option but I've always had a thing for GP bikes and this seems like the best real-world option. The end product is a 250 lb race bike with around 70 hp.
Here's the link to one of the companies that makes the conversion kits:
GP Tech out of the US also makes a kit as well as ready to ride bikes:
Theres a few Real GP Bikes for sale I would sell mine possibly . Lots of TZs 250s and HRC 125s for sale in the states .
