Can anyone tell me how the gk71b 400 handle/ performs from personal experience??

Cheers!

Was a good little bike at the time.
So long as you understand it's old and has skinny tyres you will be ok.
One of the classic mags did a test on the older model 4's and the suzi topped the test.

Oh I'll try find that article, yeah the tyres are abit to thin for my liking
