Brammo has been recently testing their TTR prototype which will be raced at the 2009 all-electric Isle of Man TTXGP and took the opportunity to shoot two teasing videos which not only show that the bike can be fast and look aggressive (note that it doesn’t get the final touches yet), but sound unbelievable good too. We’re simply amazed by the two rather fast passes and the sound that they’re accompanied by!

See videos after the break.
