Honda SH300 SH300i 2007-2015 Scooter Manual

TheBikeMarket's own collected owner reviews confirm exactly why this bike genuinely converted so many riders up from smaller-displacement scooters. One owner's account is worth quoting at length: "I took the bike back to Honda for its first service and while I was there I enquired as to whether there was any way to make it more powerful. I was shown a Honda SH300i and a test ride was arranged. The difference was phenomenal. I can recommend the SH125 if you are just commuting, but if you are interested in riding any distance which includes motorways, you really need a 300cc machine!" Another longtime owner confirms genuine long-term brand loyalty across multiple SH generations: "I purchased my first Honda SH300i in 2008 and was really happy with it... this year I decided (due to a bad hip) to go back to a twist and go / step through. My new SH300i is a lovely bike and I am delighted with it."

Power throughout this exact range comes from a 279-283cc liquid-cooled single-cylinder four-stroke engine managed by Programmed Fuel Injection (PGM-FI), delivering a claimed 27 hp at 8,250 rpm and roughly 19 lb-ft (26 Nm) of torque at 6,000 rpm. Autoevolution's own confirmed production history flags a genuine mid-run generational split worth knowing before assuming universal parts interchange across this whole 2007-2015 span: "the first major overhaul occurred in 2011, when the scooter received all-new bodywork and a new wheel design. Other changes were made to the chassis, frame, and suspension" — real hardware distinctions between a 2008 example and one from 2012 onward, well before the more comprehensive Euro4 update that arrived right at the tail end of this range in 2015.

TheBikeMarket's own confirmed owner testimony offers genuine real-world performance data: "it is quick away from the lights and capable of a little over 90 mph. With the strong performance also comes a good mpg. Honda claim over 90 mpg, but I've been getting somewhere in the late 70's due to not be able to resist the excellent performance!" That same source confirms genuinely strong braking hardware carried consistently across this generation: "the brakes are fantastic with the hydraulic linked system," a real safety feature distinguishing this platform from budget-tier commuter scooters of the same era.

Autoevolution's own confirmed technical account flags the genuine engineering work Honda applied right at the 2015 boundary closing out this exact range: "an updated engine for Euro4 emission standards, full LED lighting, more storage under the seat, and two-channel ABS as standard. Some other changes included increased torque that offered instant acceleration in the low-to-mid range, and the fuel economy was also improved by using low-friction technologies and bearings. This was Honda's first Euro4-compliant unit" — genuinely significant, since this makes the 2015 model year a real transitional point between the original 2007-2014 architecture this manual primarily covers and the further-updated 2016-2020 SH300i that followed. TheBikeMarket's own confirmed 2015-model specification lists a claimed 24.8 hp at 7,500 rpm on that updated engine — a genuine, if modest, output reduction versus the earlier 27 hp figure, reflecting Euro4-driven recalibration rather than a performance regression. Standard equipment throughout this range included 16-inch wheels front and rear — TheBikeMarket's own owner testimony confirms "I really like the size of them at 16in and they give you a nice safe feel on the road" — a genuine touring scooter riding on genuine touring-scale wheels rather than the smaller 10-13 inch wheels typical of lighter commuter scooters.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2007-2015 SH300i running the way it was built to.
