The Yamaha R15's 155cc liquid-cooled engine with VVA spins to 10,000 rpm, giving it a genuine supersport character that comes alive on the twisty climb from Lamai to the Lad Koh viewpoint. A committed 815 mm seat, clip-on bars, and 141 kg kerb weight make it the fleet's sharpest small-capacity sport bike for riders who want to lean into Samui's coastal bends.
R15 units are the sharpest small-capacity sport bikes here, and the riding position tells you so before the engine does. Clip-on bars, rear-set weight distribution and a tall seat put you forward over the front wheel, which is exactly what makes the coastal bends satisfying and what makes a slow traffic crawl tiring. The liquid-cooled 155 spins hard and rewards being kept in its upper range, aided by a deltabox frame and upside-down forks. Nothing about it is arranged for comfort or for carrying a passenger any real distance.

The consistent recommendation is to rent it for a specific kind of ride rather than as general transport. Dry tarmac, the sweeping inland route and the viewpoint climb above Lad Koh are where the whole machine gets used, and a focused half day there beats a full day of errands on it. The advice on riding it well centres on the revs, since the power arrives high up and the temptation is to chase it, plus full protective gear given the commitment of the position. Riders wanting more torque and a comfortable pillion look at the larger Kawasaki instead.
