Suzuki GSX1300R Hayabusa Gen 3 2021-2024 Service Manual

Rider Magazine's own first-look review is precise about the genuine scope of this generational change: "although it is not a from-the-ground-up redesign, there are substantial changes to the platform. The first change is to the name, which ditches the GSX1300R tag and opts for what the rest of us have been calling it, the Suzuki Hayabusa." MCN's own review confirms just how significant this bike's continued existence really is: "it's the only high-performance hyperbike still on sale in 2024" — and MCN's own model timeline traces the lineage back through a genuine four-year gap, since Euro4 emissions rules had forced the Hayabusa off European showrooms entirely from 2018 until this third generation's 2021 revival.

Power comes from a heavily revised 1,340cc liquid-cooled inline-four, delivering a claimed 187-190 hp at 9,750 rpm and 110 lb-ft of torque at 7,000 rpm — Rider Magazine's own coverage notes this represents a genuine seven-horsepower drop and nearly 4 lb-ft torque loss versus the outgoing second-generation bike, "undoubtedly" attributable to stringent Euro 5 compliance, though Suzuki deliberately traded peak output for stronger real-world usability: "compared to its predecessor, the 2022 Hayabusa pumps out more power on the bottom-end and midrange puff, and for real-world street riding, that's where you need power the most." Virtually every internal component received attention: a revised cylinder head, new throttle bodies, revamped cam profiles, optimized oil flow, stiffer valve springs, lighter and stronger pistons and connecting rods, new magneto timing for improved cold starts, and a new assist-and-slip clutch, all exhausting through a new 4-2-1-2 system that's 4.5 lbs lighter than before. MCN News' own Australian launch coverage details a genuine engineering borrow from Suzuki's sportbike program: "borrowing technology used on the GSX-R1000, changes to the crankshaft oil passages deliver oil more efficiently to the connecting rods," achieving a 54% improvement in oil flow and pressure at the crank without any changes to the oil pump itself.

Autoevolution's own coverage confirms the sheer scale of the update: "for the 2021 model, the bike maker added 550 new or redesigned parts," alongside genuinely modern electronics including Launch Control, Hill Hold Control, and Emergency Stop functions — a full electronic rider-aid suite that MCN's review found makes "a very approachable weapon" out of what remains a genuinely serious hyperbike. Braking steps up to Brembo Stylema front calipers on dual 320mm discs, tied into Suzuki's Motion Track ABS, riding on exclusive Bridgestone Battlax Hypersport S22 tires. MCN's own long-term owner reviews flag a few genuine real-world niggles worth knowing: snatchy low-speed throttle response blunted somewhat by the electronics, and a riding position that can feel cramped for taller riders — though one longtime French owner's own testimonial captures the broader consensus well: "the gen3 is a real improvement on the previous versions: handling, the bike feels lighter... precision and stability in curves have been improved, braking is very effective and smooth." This generation carried forward through 2024 with only new colorways and a 25th Anniversary special edition in 2023 — no further mechanical changes to the core platform.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2021-2024 Hayabusa Gen 3 (GSX1300R) running the way it was built to.
