Triumph has updated the Street Twin and Street Scrambler in its Bonneville range – and we’re talking about proper updates here, not just new colours. Power of the 900cc liquid-cooled, eight-valve, SOHC, parallel twin engine – which the bikes share – goes up by 10bhp to 64bhp, whichmeans 18% more peak power than before. The red line is also 500rpm higher as a result, while maximum torque is 59t-lb. he engine updates include a new magnesium cam cover, new lightweight crankshaft, dead shafts and balance shafts, a new mass optimised clutch cover, and a lighter clutch.
Small Triumphs get big muscles
It’s not just the engine that has been upgraded: both bikes now have a Brembo four-piston front brake caliper, and new higher-specification 41mm front forks. he Street Scrambler also boasts wide bars, forward set pegs, a 19in front wheel, and dual purpose tyres, while the Street Twin (Triumph’s best selling modern classic) retains its more road-oriented look with its 18in front wheel.
Behind the retro looks both models hide clever tech such as new Road and Rain riding modes, switchable ABS and traction control, torque-assist clutch, LED rear light, immobiliser and USB power socket. The Street Twin also has the capability to bolt on a tyre pressure monitoring system as an accessory.
The bikes’ looks have been updated with a new logo, new instrument styling, and improved finish and detailing. The Street Scrambler gets a new adventure-oriented seat finish and wider spaced front forks for more Scrambler-style presence and poise, while the Street Twin gains newcast aluminium multi-spoke wheels with machined detailing. For an extra bit of individuality, you can opt for one of the ‘inspiration’ kits (available for both models), which add a new look to the bike with one swift installation.
