A decade has gone past since the Street Triple first broke cover. Mimicking the Speed Triple 1050 at the time, it didn’t take much more than the twin headlamps and underseat exhaust to win hearts. Superficially, there was much to like but underneath the street naked was the heart of a supersport, the Daytona 675. Agility, quickness and affordability were its USP that made for 50,000 units sold so far. Now in its third generation the Street Triple has raised the bar again, aiming to set new standards.Engine:From two versions in its previous iteration, the all-new Street gets three versions to choose from with each offering unique characteristics to suit varied use and riders. The 675cc engine from the Daytona continues to be the base with its in-line, three-cylinder motor’s capacity being bumped up by 90cc to now total 765cc. Power has risen from 109bhp to 113bhp in the new Street Triple S while progressively increasing to 118bhp in the R and 123bhp in the top-specced RS trim. To achieve this, 80 new components have been used including an obvious increase in bore and stroke to achieve the capacity increase.Now in its third generation the Street Triple has raised the bar again.A new crankshaft, pistons, connecting rods, balancer shaft and aluminium cylinder barrels with Nikasil plating that assists smooth piston action during the initial few thousand kilometres. The aluminium sleeves come in place of iron ones in the 675cc Speed Triple.Power:The power curves display a visible increase in horsepower output starting a shade over 4,000rpm and continuing onward beyond 11,000rpm where the curve tapers off compared to the old engine. Torque too sees a surge above 4,000rpm and remains nearly flat till 10,500rpm before tapering off.advertisement5-inch TFT colour screen on R and RS models, the base S trim gets digi-analogue instrumentation from the outgoing motorcycle.Triumph claims a 6.6 per cent and 7.3 per cent bump in peak power and torque outputs respectively in the base S trim while the RS gets a substantial 16 per cent rise in power and 13 per cent in torque starting before 3,000rpm. The gearbox also receives revised geometry for smoother shifts and shorter 1st and 2nd gears for better acceleration, with assistance from a slipper clutch.Suspension:Cycle parts also see major revisions to the suspension. The rear swingarm is new, claiming to increase torsional stiffness and improving lateral flex with the aim to achieve stability at higher speeds. The front suspension is top-notch with Triumph choosing non-adjustable Showa Separate Function Forks for the S and fully adjustable 41mm Showa Big Piston Forks for the R and RS, the latter using the highest specification for the front and fully adjustable Ohlins STX40 monoshock at the rear for track duties.R gets riding modes like Rain, Road and Sport, RS adds a Track mode. All modes offer full power.Verdict:Triumph has upped its game in the supersport street-naked class. Already touted as best-in-class, the Street Tripe now comes with a choice for every type of rider. The S appealing to newer riders, the R with a seemingly formidable street package and the RS taking up track duties too.
