Inline-Four Power. Lightweight Agility. Pure Thrill.
A high-rev inline-four heart with a 14,000 rpm scream, delivering a one-of-a-kind soundtrack and top-end excitement in its class.
443cc inline-four engine making 66.6 hp at 13,250 rpm, paired with a 12.9:1 compression ratio for explosive top-end performance. Adopts DLC-coated components to minimize friction, ensuring outstanding high-rpm stability and durability.
With specific calibration of the intake/exhaust system and valve timing, the 450RR delivers a sound character that feels almost “mechanically super charged-like”: dense and smooth at idle or low speeds, then sharp and forceful as the revs climb. At the back end, there’s just 49mm of movement, with the monoshock again being fully adjustable. There is a 220mm single disc, and one-piston caliper, again equipped with ABS functionality. Seat height is adjustable between 780 and 795mm.
This is enabled by our world-1st 3/4 Frame, weighing just 7kg, improved upon using race data from KOVE's racing Centre. Delivers a 27% gain in rigidity and torsional resistance. The chassis cuts on bulk, improves the balance of the motorcycle and gives you quicker, more confident cornering capabilities.
24.5° rake angle + 98mm trail for golden handling geometry, matched with 28° steering angle and 1385mm short wheelbase: quick, precise steering, agile at low speeds, and stable in high-speed corners.
Winglets - Subtle Downforce You can Feel At speed, the bike stays calmer and more planted. When you lean in, it feels like an unseen hand pressing the front tire into the tarmac, boosting stability and confidence. Side Panels - A Tailored "Riding Suit" Let your legs lock in closer to the bike for a more unified feel, helping reduce turbulence and improving comfort and steering precision.
Optimized ergonomic triangle with adjustable 785mm-795mm seat height fits the riding posture, softens the aggressive stance, cuts down handling fatigue, and achieves seamless man-machine integration.
