Aye Joolz,

You could also try this KTM look alike: 'EFI_500' (http://jutmotor.en.ec21.com/EFI_500cc_Motorcycle--1004880_3975208.html)

Spoke wheels on background machine in one of the shots.

Note to 002, you could bring in 24 in a 20' shipping container!  ;)

Regards, Bill.

Was getting a bit interested reading through the spec then, it was sounding a fair bit like the SRX then I scrolled down as far as the picture - ain't exactly pretty is it? :-\

wonder how long it'll be before they start making reliable bikes. i see chinese nasties (as they have become known) come into the yard on a regular basis with massive catastrophic faliure of the engine. the worst one being a dead 125 after 70 miles from brand new! be good if their quality improves and they continue to make this sort of thing as i should be able to stock up on cheap engines then :) love the fact that the efi has a forged aluminium piston

I have worked on Chinese bikes and yes the reliability and build quality are the worst possible
