Mounting that size of time clock onto any bike would never be my choice, does not really enhance looks I feel. i would be in doubt of even fitting a rev counter, a speedometer is the legal minimum, so be it. So one of the hundreds of handlebar clocks at Ebay at no money would be possibly acceptable as it is small enough not to spoil looks.
