How Much Power Does the 2024 Montesa Cota 4RT 260R Make?

Dyno testing Montesa Honda’s smallest-displacement trials bike for horsepower and torque.

Trials motorcycles are specialty machines designed to conquer the gnarliest off-road terrain imaginable, even where one cannot travel on foot. Some unique aspects about trials bikes compared to their dirt bike counterparts are a lack of a seat, conventional fork, and chassis that’s designed to be hopped and take riders over obstacles of all sizes.

Engines and the type of power they produce are another aspect that distinguishes trials bikes. Most manufacturers still primarily offer two-strokes, but some such as Beta have thumpers in their lineups. Montesa, on the other hand, has been all four-stroke since 2005 when it introduced the Cota 4RT. From then until 2013, it was a fuel-injected liquid-cooled SOHC four-stroke 249cc single-cylinder engine. In 2014, Montesa increased its displacement to 259cc.

We know trials bikes are designed for instant torque at low rpm, but we hadn’t dynoed one with a four-stroke mill to see exactly what a thumper intended for this type of riding is capable of in terms of empirical data. That changed when we rolled the 2024 Montesa Cota 4RT 260R onto our in-house Dynojet 250i rear-wheel dynamometer, where it made 15.6 hp and 13.4 lb.-ft. of torque—both at low engine speeds of 6,500 rpm and 5,500 rpm, respectively.
