Triumph Street Triple 675 2008-2012 Service Manual

Since its launch the Street Triple has been a global hit, fusing the style and attitude of the iconic Speed Triple with the performance and agility of the class-leading Daytona 675 supersports machine. It shares parts with the Daytona, mainly in the aluminum twin-spar frame and swingarm, and at 167 kg dry it’s a lightweight, easy-to-manoeuvre bike. The 2008-2010 bikes have the twin round headlights and a 41mm KYB upside-down fork, and the R version adds a fully adjustable fork and a piggyback rear shock for a more aggressive riding position (with a seat 5mm taller). For 2012 the circular headlights changed to an angular shape in line with the Speed Triple’s new look, with redesigned side casings, a brushed aluminum finish around the exhaust and black rear sets, and ABS became an option on the 2011-2012 R. Owners rate it highly, and its top speed is about 139-141 mph.

The engine is a 675cc liquid-cooled DOHC inline triple with four valves per cylinder (12 in all), a 74mm x 51-52.3mm bore and stroke and a 12.65:1 compression ratio. Multipoint sequential electronic fuel injection with forced air induction feeds it, and the exhaust is a stainless steel 3-into-1 with a low single-sided silencer. Triumph claims 105 hp (78 kW) at 11,700-11,850 rpm and 68 Nm (50 lb-ft) of torque at 9,200-9,750 rpm. The gearbox is a six-speed with a wet multi-plate clutch and chain final drive.

The frame is an aluminum beam twin-spar design with a KYB 41mm upside-down fork (about 120mm of travel) and a KYB monoshock with adjustable preload (about 126mm of travel). Brakes are twin 308mm floating front discs with Nissin two-piston sliding calipers and a 220mm rear disc with a single-piston caliper. Tires are a 120/70ZR17 at the front and a 180/55ZR17 at the rear.

The Street Triple is about 1,999mm (78.7 inches) long and 734mm (28.9 inches) wide, on a wheelbase of about 1,389-1,410mm (54.7-55.5 inches). Seat height is 800mm (31.5 inches), or 805mm on the R. The tank holds about 17.4 litres (4.6 gallons), with a range of about 145 miles, and engine oil capacity is about 3.4 litres. The Street Triple weighs about 167 kg (368 lbs) dry and about 182 kg (400 lbs) wet.
