What makes each one tick

Bonneville T120

The Bonneville T120's liquid-cooled twin shoves hard from low down, its pipes thumping out an offbeat bark. At corner entry the bike carves into a backroad bend on that smooth drive, and the upright bar doesn't fold you over the tank. There's no fuss in town. Its deep paint gleams at every gas stop.

Bonneville T100

A charismatic throb comes off the Bonneville T100's twin as it hauls hard out of slow corners. It doesn't take much push at the bar, and with its weight carried low the bike drops into a winding back road without a wrestle. Bumps don't throw it wide.
