The XSR900 GP Is Finally Coming to America, and a Smog Filing Gave It Away

Yamaha has not announced anything. What exists is an executive order from the California Air Resources Board, dated August 3, certifying two versions of the XSR900 GP for sale as 2027 models. The codes on the filing are XSR9GPVCW and XSR9GPVCY — the V for the 2027 model year, the C for California certification, and the last letter for the color. W is white. Y is yellow.

That is a thin document to build a story on, except that emissions certification is the step a manufacturer does not take for a bike it has no intention of selling. Federal EPA certification normally follows. For American riders who have spent two years watching European reviews of a Yamaha they could not buy, the CARB order is the closest thing to confirmation short of a press release, and the press release is expected in the coming weeks.

The XSR900 GP went on sale in Europe as a 2024 model and stayed there. It is the standard XSR900 — itself the retro-bodied version of the MT-09 — rebuilt around a half fairing, a bubble screen, clip-on handlebars set below the top yoke, and a solo-look tail section. The riding position moves forward and down. The tank and side panels get a paint scheme with speed blocks on it. It is, unapologetically, a modern roadster wearing a 1980s Grand Prix costume, and Yamaha has never pretended otherwise: the display card next to the bike at the Japan Mobility Show in 2023 said in as many words that the design expresses the racing history and traditional spirit of the 1980s Grand Prix scene.

Mechanically it is the CP3 platform, unchanged. The 890cc liquid-cooled DOHC inline triple that also powers the MT-09, the Tracer 9 and the YZF-R9 makes 117 horsepower at 10,000 rpm and 68.5 lb-ft at 7,000. Yamaha's own show placard listed the same engine at 87.5 kW and 93 Nm, which is the metric way of saying the same thing.

The chassis is where the GP separates from the base XSR900 beyond the bodywork. KYB 41mm fully adjustable forks with 5.1 inches of travel, split so that compression damping is adjustable on its own; a KYB rear shock with 5.15 inches of travel, remote preload adjustment and separate compression settings; a Brembo radial master cylinder feeding four-piston calipers on twin 298mm front discs, with a 245mm disc at the rear. The swingarm is 2.3 inches longer than the MT-09's, which is a stability decision rather than a styling one. Seat height is 32.8 inches, wheelbase 59 inches, wet weight 441 pounds.

None of that is new — it is the European bike, brought over intact. What is new is that it will be sold here, in a class that has quietly thinned out. The half-faired retro sportbike has been mostly a European and Japanese product for a decade; the American version of the category has been either full-fairing supersports or naked roadsters, with very little in between that is not a Triumph.

Two things the CARB filing does not contain: a price and an on-sale date. The GP has consistently carried a premium over the standard XSR900 in Europe, which the Brembo and KYB hardware accounts for, so expect the same shape here. As for timing, a 2027 model year designation generally means dealer floors in late 2026 or early 2027.

The other Yamaha item worth noting from the same certification round is the XSR155, a much smaller retro that has also turned up in 2027 US paperwork. Between the two, Yamaha's sport heritage line in America is about to get both its cheapest entry and the one people have been asking for by name.
