Suzuki has released full technical details of its 2019 RM-Z250, with the MX2 machine getting a new frame, swing-arm and suspension, plus a new engine that produces more power and torque than its predecessor. The new RM-Z250 also gets the latest version of Suzuki’s Holes-hot Assist Control and traction management systems, further improving its performance, while more angular new styling sharpens the look.
With a focus on improving both power and manageability, the 2019 RM-Z250’s engine has undergone significant enhancements. Peak power is improved thanks to a newly-designed cylinder head and new intake and exhaust ports which increase airflow and combustion efficiency.
Weight reduction was a key objective for Suzuki engineers during development, whilst improving the 2019 RM-Z250’s handling performance. A new frame retains fore-aft rigidity, running the length of the bike, but increases torsional rigidity by 10%. It also reduces weight by 370g.
Fully-adjustable suspension is again provided by KYB, with spring forks replacing the air forks on the previous generation, and a new rear shock. There are also further weight reductions, thanks to a lightweight spring with thin wire diameter, derived from MotoGP knowhow. This reduces weight by 370g, while the rear suspension linkage is reduced in weight by 15g.
The 2019 RM-Z250 stops better than its predecessor, thanks to a larger front brake disc, which goes from 250mm to 270mm. New brake pads give a more linear feel in response to rider’s input at the lever, and there is a new rear brake master cylinder which improves operation, better prevents dirt entering the system, and is designed to better prevent the rider from catching it with their boot.
Turning and handling performance is further enhanced courtesy of lighter rims, with a new front rim 40g lighter and 60g saved with a new rear rim. The new rims are also shod with new Dunlop MX33 tyres for greater traction.
Suzuki’s advanced Hole-shot Assist Control and traction management systems are further improved for 2019, giving riders a better chance to get out of the gate ahead of the competition and stay ahead in the race.
