Significantly updated for 2021, the Speed Twin’s distinctive 1200cc high power Bonneville Twin engine now boasts even higher performance, as well as lower emissions, making it fully Euro 5 compliant. The engine now delivers 3PS more peak power with 100PS at 7,250rpm, as well as more power in the mid-range than the previous generation.
The 2021 Speed Twin also gets a fuller torque curve, with 112Nm of peak torque being less than 500rpm from the rev range compared to the previous generation.
Speed Twin engine responsiveness has also been enhanced, thanks to a 17% reduction in inertia achieved through a new lightweight crankshaft and alternator. These enable the engine to spin faster than the previous generation, and spin harder for longer periods of time, with a red line now 500rpm higher than before. In addition, new high compression pistons, revised ports and a new cam profile round out the list of performance enhancements.
The Bonneville Twin’s distinctive sound is enhanced by the new brushed stainless steel Megaphone Twin upswept sports silencer, which has been carefully crafted to a deep, throaty roar to match the Speed Twin’s legendary name. The innovative and unobstructed exhaust header run cleverly hides the trigger box, providing the distinctive clean-line “straight-run” design.
The cost of ownership is kept low due to the high first major service interval of 10,000 miles/16,000 km.
The new generation Speed Twin benefits from a number of significant upgrades for an even more precise, agile and dynamic ride.
New for 2021, the Speed Twin is equipped with upside down 43 mm Marzocchi front forks with cartridge damping, which brings a more confidence-inducing and comfortable ride along with 120 mm of wheel travel. These are perfectly matched to the twin rear suspension unit with adjustable spring preload, and 120 mm of rear wheel travel, both of which have been precisely tuned for superior handling and the perfect modern roadster ride.
Further enhancing the new generation Speed Twin, braking performance is improved with new high specification Brembo 4-piston M50 radial monoblock front brake calipers and twin 320 mm Brembo discs. With a Nissan 2-piston floating rear caliper with 220mm disc and ABS fitted as standard, these offer a stronger initial braking-bite, more feel and better fade characteristics.
Ensuring incredible grip, precision and high-speed stability, new Metzler RaceTech RR tires are fitted as standard for the 2021 model, along with new cast aluminum wheels, 17” at both the front and rear, lightweight 12- With spoke design.
A beautifully balanced motorcycle, the Speed Twin brings a smooth and confident ride. Ergonomics are perfectly proportioned with an accessible 809 mm seat height, a slim stand-over width, tapered handlebars and a comfortable roadster foot-peg position, which are 38 mm forward and 4 mm lower than the Thruxton, giving the rider greater comfort. provide. riding position.
