Friday bike

A bike we should be seeing later this year:


A surprising bike from BMW being of such small capacity, their smallest bike since the R27 of the early/mid 60s. Built in partnership with Indian firm TWS, the G310R has a 313cc single cylinder engine with its cylinder angled back and a rear exiting exhaust. Will be interesting to see how it compares with models from Japanese and other European manufacturers.
