The liquid-cooled, fuel-injected powerhouse is paired with a 5-speed gearbox, providing seamless shifting and making it easy to find that perfect gear for any terrain. The bore and stroke measurements of 95.0 mm by 63.4 mm further enhance the engine's performance characteristics, allowing for a remarkable power-to-weight ratio of 0.6087 HP/kg.

The central double-cradle-type frame made of 25CrMo4 steel provides exceptional rigidity while keeping the weight down to a mere 103.5 kg. The WP XACT suspension systems—both front and rear—offer 310 mm and 300 mm of travel, respectively, allowing for superior handling over rough terrain and responsiveness to rider inputs. With a rake of 26.1° and ground clearance of 343 mm, this bike is agile and ready to tackle tight corners with ease. The electric starter adds convenience, letting you fire up the engine with the push of a button so you can focus on the ride. **
