Triumph’s Street Triple platform is one of our favorite motorcycles because of its playfully sporting character that appeals to all sorts of riders. In fact, the up-spec R version took our Motorcycle of the Year honors in 2009. So when we learned about an updated version for 2013, we were hoping Triumph didn’t do anything to diminish its eminently likeable qualities.
Measured by the sum of their parts, the 2013 Triumph Street Triple and Street Triple R are more than warmed up 2012 leftovers. The lauded 675cc inline three-cylinder returns unchanged, but the obvious relocation of its exhaust system is only the tip of the proverbial iceberg. From frame to wheels nearly everything besides the motor powering these naked hooligans must be preempted with the word “new.”
To begin, not only is the reengineered exhaust system 7.9 pounds lighter than the one it’s replacing, the weight is centralized closer to the engine to make quick transitions even quicker. Also helping the S3R’s improved flickability is a lighter by 1.1 pound rear wheel, 1.1-pound lighter rear caliper and a 1.3 pound lighter swingarm (an all-important unsprung weight advantage of 3.5 pounds). A 1.8 pound lighter subframe and tail section assembly brings the total combined weight loss to more than 13 pounds on non-ABS models.
Also contributing to the Street Triple R’s newfound agility is a redesigned frame constructed from three fewer parts. The new frame decreases the R’s rake by 0.5° (from 23.9° to 23.4°) and adds 2.6 mm of trail (from 92.4 mm to 95mm). There’s also a more forward weight bias, from last year’s 49% front, 51% rear, to 2013’s 52% front, 48% rear balance. Steering radius increases from 28 degrees to 31 degrees to make it more maneuverable in tight spaces. An adjustable swingarm pivot is a feature of only the R model.
Impressive as all these changes may sound (and they are), any rider of novice credentials considering the Street Triple or Street Triple R shouldn’t feel overwhelmed by the bike’s changed geometry. On the contrary, the new Street Triple exhibits such composed, neutral handling it’s docile by supersport standards. But when piloted aggressively the Street Triple – especially the R model with its fully adjustable Kayaba suspension components – dices a tight canyon road with the acumen of a Masamoto sushi knife.
The Street Trip’s taller first gear lessens the amount of upshifts required when riding short distances between stoplights. And the bike's fueling, whether at moderate in-town speeds or screaming up the side of a mountain, delivers an uninterrupted flow of gas and air with no hiccups or dips in power.
Braking performance from the R's four-pot Nissins is substantial and easily modulated. The shorty levers attached to our demo model stretched the extent of my reach even when adjusted to their minimal setting.
With the optional Arrow exhaust installed – a further 1.8 pound weight reduction and claimed increase of 2 horsepower – the Street Triple R emits an ear-pleasing three-cylinder warble at a respectable decibel level with the baffle removed. Riding an S3R with the stock exhaust, there’s a noticeably enhanced sound coming from the airbox courtesy of a new intake system. Other engine modifications include new throttle bodies and EFI calibrations which, according to Triumph, boosts urban fuel economy by a massive 30% (33 mpg to 43). That sounds wildly optimistic to us, but we’ll have to wait until we test one at home to find out for sure.
Because the rear subframe no longer supports the weight of the exhaust, Triumph was able to redesign the component using new high-pressure die-casting that shaves 1.8 pounds of weight. The redesign also allowed for increased storage room beneath the seat, enough to conveniently fit a U-lock. All R models feature a red subframe, matching red radiator cowls and red pinstripe wheels, while the optional-on-the-standard-model rear hugger fender is standard equipment on the R.
Beyond cosmetics, what separates the standard Street Triple from its R brethren is non-adjustable suspension, 2-piston front calipers (vs. 4-piston radially mounted calipers) rake and trail figures of 24.1°/ 99.6 mm (vs 23.4°/ 95.0 mm due to suspension differences) and a lower seat height of 31.5 in (vs. 32.3 in due to suspension differences).
Both models are scheduled to arrive in January. Color selections for the standard model are Phantom Black, Crystal White and Caribbean Blue, while the R model offers Matte Graphite in place of Caribbean Blue.
