PGM-FI engine

The bike has a fuel-injected power system that's easy to control for Trials riding. The 298cc Honda liquid-cooled four-stroke engine is tuned for low-rpm response and, thanks to a high-pressure fuel pump, provides ample power and torque across the rev range.

Three-ring piston

A three-ring piston allows for better sealing and improved durability. The piston is light and designed with a flat top, reducing vibration and making combustion more efficient at low rpm.

Premium suspension

The 4RT 301RR features a Showa ® fork and a Showa ® rear shock designed to improve handling and overall feel.

Chassis

It uses an aluminum chassis with a stunning finish, a reinforced muffler, and a short rear brake pedal for more freedom of movement.

Brakes and wheels

The bike comes with a four-piston monoblock front-brake caliper and 32-spoke wheels. The rear wheel features a central adjustment spokes system that reduces weight and allows tubeless rear tire installation.

Dual-map ECU

A handlebar-mounted mode switch lets you choose between two maps/modes to change engine power delivery. The bike even includes special ECU mapping that improves engine response in the low- and mid-rpm ranges.

Advanced engineering

The Honda engine used in the 4RT 301RR features a battery-less digital ignition system, a bank-angle sensor that turns off the ignition when the motorcycle is lying on its side, and a magnetic kill switch.

Kickstart lever

The bike features a long kickstart lever, helping ensure easy one-kick starts no matter where you are on the course.

Updated styling

Its bodywork showcases a striking new color scheme for 2026, featuring light green, magenta, and white, creating a look that’s both eye-catching and distinctly Montesa.
