Triumph Street Twin 2018

Triumph Street Twin 2018

The new Triumph Street Twin cleverly continues the success story of the predecessor model; instead of radical changes, there are targeted improvements to the engine, brakes, chassis and ergonomics. The enormous 10 hp increase in power is nice, but the special character of the powerful in-line two-wheeler is still experienced more in the mid-range. Added to this is an improved look and feel at a price that is hardly higher. If you have too much money in your wallet, you can pimp and customise your Street Twin with almost 140 original accessories.
