Sweet score uk.... :thumbwink:
The Derbi GPR is highly prized here by those in the moped(not scooter) culture.
Rode with one in a recent rally and the performance is impressive.
Please DO continue with this post.... :hi:

theres a few things i need to get done to get it 100% road legal, i need to source a headlight and headlight fairing, lower side fairings, front mudguard, rear light lense, mirrors, new front tyre, rear suspension as it is slow to return as the mot tester told me this morning, rear brake needs adjusting somehow then thats it for the road legal bit.

thanks, when you say the performance is impressive you aint lying, i was hitting 60mph without absolutely ragging it, i pushed it as far as i dared but im sure there was a little more topend there, its in the garden now being completely stripped down, cleaned and rebuilt, taking lots and lots of pictures, ill update as i go along.

got a set of twin headlights coming, a rubber clock encloser to keep the wiring dry, gonna do sort of a streetfight/naked look on this one, gonna get front mudguard but going to leave the front light fairing and lower side fairings off, looks nice as it is i think, got the wiring loom out now just figuring out whats what, so far ive figured out the rear light, indicators and cdi but thats all lol

sorry about not taking and uploading any pics my camera has broke, the screen just stays blue when i turn it on so back to nikon it goes, ive finished wrapping the wiring loom and it looks ALOT better and tidier now, hopefully ill be able to put it back in the bike tommorrow and ill try taking pics with my spare camera, the bodywork will be coming off for a while, while i flush the radiator and figure out what hoses go where, going to remove the thermostat too as its one of the favoured mods over here (redvisionmonster owned one before and says it can pack up easily so he took his out and put a washer in and no problems since) so im going to try that, new rear light and a twin headlight is on its way, getting a new chain put on and hopefully itll be road legal by the end of next week ready for walsallmopeds ride :smile:
