Hi there, the B1 rep is advertised to be 14bhp, but infact is only 4bhp from standard, with an upgraded carb, reeds, ect. you could push it to 6bhp. I have been told this by somebody who has put one on a dyno.
The GP3 rep is 6.4bhp as standard, with a simple carb kit they will go to 8.5bhp. This i have seen with my own eyes.

Overal the GP3 is better desighned, faster, and handles better. But they are a very small bike, and a lot of people cannot ride them comfortably so they chose the B1 rep.
You are best to try a GP3 first before you ride, you are welcome to try mine.

Correct me if i'm wrong anybody??????

i dont no if i could try your bike cos i live in warrington and thats miles away from u. i may be able to try one because theres a kartin track near me and sum1 might have one and let me have ago.

I've got a dyno graph on my other pc which shows a totally standard, out the box B1 rep, with 8.3 horses, I'll post the graph later on when i go on the other pc

I would not believe it was out of the box, as i have ridden a standard GP3(6.4hp), and my B1 rep that was extremely quick and was only pushing 6hp, and tuned as much as possible.
Also Scott finlay from minimoto Racing actually told us he has never been able to tune a B1 to more than 8hp. And most of them are only 4hp..

There we go

nice graph but it dont say its a b1rep any where on it? and it also reached peak power at about 28mph then died off

Hally! Remind me what sort of torque did Scotty get out of our GP3's?
