Last year CFMoto launched its 250SR and 300SR sportbikes—a brace of single-cylinder race replicas to compete with the likes of Honda’s CBR300R—and now the firm is about to debut a higher-spec machine in the form of the new SR-R. The existing 250SR and 300SR are identical in all but their capacities, with the smaller version reserved for markets with license or insurance categories based on engine size, while most countries get the bigger 300SR. Despite their different capacities, both bikes make virtually the same amount of power and share identical dimensions including a ready-to-ride weight, fully fueled, of 165 kilograms (364 pounds). Now, a new Chinese type-approval document has revealed the existence of the uprated 250SR-R, and inevitably there will also be a 300SR-R version for markets that currently get the larger model.
For decades we’ve been trained to recognize that an extra “R” means a sportier model, with Honda’s latest CBR1000RR-R taking that philosophy to the extreme, and the CFMoto SR-R is no exception to the rule. According to the type approval, its engine is the same as the Chinese market version of the 250SR, with 21.5kW (29 hp) on tap, but it will still offer a performance increase thanks to a significant reduction in weight. The curb mass drops from 165 kilograms to 157 kilograms (346 pounds) including fuel, suggesting the adoption of some lightweight materials in elements like the bodywork, and there’s one particularly notable change to the chassis, with the adoption of a single-sided swingarm instead of the base SR’s double-sided design. Normally a single-sider will be heavier than a dual-sided swingarm, but CFMoto appears to have reversed that rule with the SR-R. To go with the new swingarm, the SR-R gets gold-colored fork, perhaps hinting at higher-spec internals, and, of course, the rear wheel is new.
The swingarm isn’t the only cosmetic change, as the SR-R also gets a particularly large pair of winglets on the sides of the fairing, either made of carbon fiber or wrapped in a carbon-effect finish from the appearance of the single photo accompanying the type-approval notification. Although any increase in downforce or reduction in front end lift is likely to be immaterial in a bike with less than 30 hp on tap and a top speed of around 80 mph, there’s no doubt that MotoGP has made winglets an indispensable fashion accessory for any bike with sporting intentions in the 2020s.
Although yet to be formally announced, the existence of the type-approval documents and the photo of the CFMoto 250SR-R show that the model is ready for launch, so it’s likely to join the firm’s range in 2022.Source link
