I found these videos online showing Brammo running their bike for the TTXGP. TTXGP is billed as the world first zero carbon GP race. It's great to see these new electric bikes proving themselves in race conditions just like their internal combustion counterparts.
One thing that I found interesting is that the bike isn't completely silent - not quite like a Testastretta with Termignonis, but pretty interesting sounding nonetheless. It sounds a bit like my Ryobi drill on steriods.
Enjoy! If you what to see more on TTXGP, they have an entire Youtube channel
