Suzuki GW250 Inazuma 2012-2017 Service Workshop Repair Manual

MotoSpecsLab's own detailed maintenance review confirms this bike's genuine long-term durability reputation directly: "the Suzuki Inazuma 250 remains a 'hidden gem' for riders who value build quality and comfort over outright speed. Its robust steel cradle frame and 'big bike' ergonomics make it an excellent commuter. Provided the maintenance schedule — particularly the specific oil volumes — is strictly followed, the GW250 engine is known to exceed 100,000 kilometers with minimal mechanical degradation." Wikipedia's own account confirms the genuine market breadth this bike achieved under three different names: "it is called the Inazuma 250 in the EU and the GSR250 in Japan... it is used by various police services including China, Japan and USA."

Power comes from a 248cc liquid-cooled inline-twin, SOHC, a 53.5mm x 55.2mm bore and stroke, and an 11.5:1 compression ratio, delivering a claimed 24-26 hp at 8,500 rpm and roughly 18 lb-ft (24-25 Nm) of torque at 6,500 rpm through a 6-speed manual transmission. Autoevolution's own model history confirms this platform's genuine role as a direct successor within Suzuki's small-displacement lineup: "the bike debuted in 2012 as a replacement model for the GW250 Thunder." 2WheelsHero's own retrospective confirms the deliberate positioning behind that engine's tuning philosophy: "the Inazuma name, meaning 'lightning' in Japanese, hints at its dynamic character despite modest displacement. The model primarily targeted urban riders and newcomers who wanted an economical, low-maintenance bike with respectable performance and quality build."

MotoSpecsLab's own handling assessment confirms the genuine riding character this chassis delivers: "the Inazuma's handling is characterized by stability rather than flickability, thanks to its generous wheelbase and tire dimensions" — Wikipedia's own spec sheet confirms a substantial 1,430mm (56.3-inch) wheelbase for the class, paired with a 37mm telescopic Kayaba fork and a Kayaba swingarm rear shock, both coil-spring and oil-damped. Braking used Nissin disc brakes at both wheels. Autoevolution's own coverage of the faired "F" variant confirms genuine market-specific configuration options: "an 'F' version, featuring a full fairing, was also available for the European market" alongside the standard naked model — the same fundamental engine and chassis dressed in different bodywork depending on regional demand.

Wikipedia's own account confirms the genuine regulatory reason this platform's European sales ended: "due to EU safety regulations, Inazuma was discontinued in Europe, as ABS is mandatory from 1/2017 for all motorcycles with more than 125cc, and there are no plans for ABS equipped Inazuma" — a real compliance deadline rather than any declining demand, with the naked GW250/GSR250 continuing in non-EU markets like Japan through 2018. Standard equipment across this range included a single headlight integrated into a fork-mounted cowl, a one-piece dual seat with pillion grab handle, a dual or two-into-one exhaust system depending on market, and three-spoke alloy wheels. MotoSpecsLab's own maintenance specifics confirm a standard YTX9-BS battery and NGK CPR7EA-9 spark plug with a genuinely precise 0.8-0.9mm electrode gap specification — real service-relevant detail for anyone maintaining this platform's electrical and ignition systems. A 13.3-litre fuel tank and 375 lb dry weight rounded out the package, with autoevolution's own pricing confirming a genuinely accessible $4,100 MSRP at the tail end of this range's production.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2012-2017 GW250/Inazuma 250 running the way it was built to.
