This neo-retro motorcycle uses the same foundations as the MT-15 in Yamaha’s Sport Heritage range.

As with its bigger brothers the XSR 700 and XSR 900, Yamaha used a traditionally styled body for the XSR 155 where they combined modern and classic elements.

The XSR 155 comes with a single-piece seat. The pillion rider can grab on to the belt positioned at the centre of the seat. The tail lamp and the rear profile features match the XSR 700.

The tear-drop fuel tank, round LED headlamp and a tan-coloured, flat ribbed seat are typical items found on neo retro motorcycles. All of these elements are supplemented by a roundel info cluster and a circular LED tail-light.

Yamaha has left the 155cc VVA-equipped motor untouched on the XSR 155, thus the performance figures are 19 hp and 14.7 Nm of torque.
