Front and rear SHOWA suspension
Ground clearance is set at 310mm and the high-quality 39mm diameter SHOWA front fork features 158mm stroke. Also, the rear SHOWA shock operates through Pro-Link. Both front and rear suspension are adjustable for spring preload and compression damping.
Aluminium side stand
The lightweight triangular-section forged aluminium side stand from the sister model Cota 301RR is inherited. It mounts close to the engine and tucks neatly underneath the swingarm well out of harms way.
Four-stroke engine
The Cota 4RT’s lightweight, fuel-injected, four-valve 258,9cc four-stroke engine delivers the smooth control and power.
Top-flight protection
The bash plate is shaped to give maximum protection to engine underside and front lower frame rails. It’s also the same design as used by the Montesa World Championship machine and constructed from identical lightweight aluminum, maintaining thickness with improved strength.
Higher performance
The Montesa 4RT 260R is equipped with the same muffler as the Cota 4RT 301RR. This exhaust gives more power at mid and high range.
New Montesa Cota 4RT 260R
The Montesa Cota 4RT began a revolution back in 2006 with the all-conquering power and torque delivery of its four-stroke engine. Always at the pinnacle of competition, and constantly evolving, the 4RT is the ultimate trials machine. This new 2026 model arrives with a groundbreaking design while maintaining Montesa’s iconic heritage red color.
It’s all about quality
The Cota 4RT is carefully manufactured at Montesa Honda’s Factory in Barcelona, northern Spain. Each machine is meticulously assembled with every part checked and rechecked for the highest quality required from a Montesa, and the function of a championship-winning tool.
Ready to go to the top?
If you want to take your competitive riding to the next level the Cota 4RT is primed and ready. Its twin-spar aluminum frame, suspension and strong engine are designed to find grip and drive in the face of what seems impossible. And a host of detail improvements – many inspired directly by the World Championship machine – plus sharp new decals keep the Cota 4RT firmly where it belongs. At the very top. Pictures show motorcycle version with Optional Race Kit and LED headlight. Both items are intended for competition use only. Visit your Montesa dealer for more information.
The art of true balance
A breath-taking climb strewn with wet, vertical rock faces. Or a gnarled descent over moss-covered tree roots. Competitive trials offer perhaps the most severe test of a motorcycle and rider – and it’s what we make the Cota 4RT 260R for.
