80cc 2-STROKE ENGINE
The proven 79.6 cc 2-stroke engine, in this Senior version, has been tuned to offer more brilliant performance than the Junior. It maintains excellent progression at low revs but guarantees the necessary acceleration to tackle the most challenging obstacles in the race.
FULL-SIZE VEHICLE
This is where the real difference lies. The Senior features a 38 mm hydraulic fork and standard competition-size wheels: 21' at the front and 18' at the rear. This configuration offers the stability and feel of a race bike.
ADJUSTABLE SUSPENSION
To adapt to different riding styles and terrains, the Senior's suspension offers greater adjustment possibilities. The monoshock, in particular, is equipped with a spring preload adjuster and a hydraulic rebound damper.
