Introduced last year, the Cota 300RR was made for competition (the "RR" suffix stands for "Race Ready") and is the production model most similar to the prototypes used by factory Honda Montesa riders. For 2017, the 300RR is even better, with new ECU mapping that improves engine response in the low and middle rpm ranges that are especially important for trials motorcycles. Another aspect that contributes to engine response is the new three-ring piston (up from two), which helps prevent leakage and improves durability. The piston is now lighter and has a flatter top, reducing vibration and making combustion more efficient at low rpm. The cylinder has also been redesigned to match the new piston, further improving engine efficiency. The chassis has also been updated, with new, suppler settings for the Tech fork, similar to those used by factory riders. Finally, the muffler is more robust with reinforced mounts, and the rear-brake pedal has been shortened to avoid impacts and allow the rider more freedom of movement.
