SPIED! 2017 Triumph Street Cup Spy Photos

Triumph is on the verge of launching this new 900cc café racer to sit towards the bottom of its retro model range, dubbed the 'Street Cup' and designed to be the missing link between the Street Twin and the 1200cc Thruxton models. It's clear from the pictures that the firm hasn't gone all-out to develop dedicated new parts for this motorcycle, instead opting to mix and match off-the-shelf components from other models in its new water-cooled parallel twin range.

Underneath, the bike is virtually unchanged from the Street Twin (click here for a video sound clip and brief overview of the Street Twin). The parallel twin engine (which we dyno'd at 52 horsepower) is identical, as is the frame, suspension and fuel tank. Even the alloy wheels are carried over from its sister bike, avoiding the overtly retro style of the wire-wheeled Bonneville and Thruxton. However, the stance is quite different. Thruxton donates its headlight, lamp brackets, seat and instruments, while the small fly screen is already an optional extra for the larger café racer.

New parts specifically developed for the Street Cup include the bars, which are low and narrow. Although they give a similar riding position to the Thruxton, the Street Cup’s bars are one piece rather than the larger bike’s clip-ons. The mirrors are mounted on the bar ends, a practice that Triumph has already adopted for the Thruxton and 2016 Speed Triple.

The exhaust system is also newly-developed and specific to the Street Cup, as is the front brake, a single floating disc in place of the Street Twin’s fixed disc and floating caliper.

The bike’s name has been revealed in Triumph’s filings with CARB and the EPA to certify the emissions of its first batch of 2017 models. In fact it’s certified three models using the same 900cc engine. As well as the already-launched Street Twin, there’s the Street Cup seen in these spy pictures and an entry-level Bonneville called the T100. It has also been seen on test and is almost indistinguishable from the 1200cc Bonneville T120 apart from the fact it has a single front brake instead of twin discs.

Given how close to production these bikes seem, it’s likely that the firm will choose to officially reveal them well before the major bike shows later this year. Triumph is known to have a host of new models under development for launch in the next few months, including a range of Bonneville-derived cruisers and a bobber as well as a completely new Street Triple range, so is expected to stagger unveilings through the year.
