Not long after spotting a 650b prototype under Dan Atherton a while ago, it appears that GT has an entirely different 650b prototype that Dan is about to race. While the first bike looked as if they had simply placed a new swing arm on an existing frame, the latest bike looks entirely new with a shock tunnel in the front triangle built in. The pivot placement also looks a bit different, so it begs the question – is the I-Drive getting a revamp? Otherwise it features a compact hydroformed rear swingarm, with an alloy front triangle to match though it could be just in aluminum as a prototype with a carbon production bike in the works. Don’t quote us on that, just a theory. According to GT, it will receive a chain retention system so that Saint ring probably isn’t a narrow-wide prototype.
Dan will be putting the new bike through its paces this weekend at the Metabief, France Open Enduro.
