CFMOTO has been releasing details of its forthcoming 675SR three-cylinder sports bike since last September, and unveiled a version virtually destined for production just a few days ago. But now the real version has appeared in Chinese homologation records ahead of its official launch. As well as revealing the final look of the bike, which is expected to be the first of several models with CFMOTO’s new three-cylinder, the documents include important specifications, including power, weight and dimensions.
Perhaps the most anticipated figure is the power output, which is not as high as expected, at 95 hp. This comes as a surprise, because when CFMOTO unveiled the engine at EICMA in Milan last year, it promised “more than 100 hp”. This seems to be an indication that the bike approved in the new documents is a restricted version. The figure of 95 hp (or 70 kW, to use the metric measurements of the homologation) corresponds to the maximum allowed by the complicated European rules for riders with a restricted A2 motorcycle license, rather than a full power approval. These A2 bikes can only produce 35 kW (47 hp) and, if they are restricted versions of more powerful bikes, these base models cannot have more than 70 kW (95 hp). As a result, many manufacturers make specific versions of 70kW motorcycles, just so that they can be restricted to 35kW and ridden by drivers with an A2 license. This is one of those cases where bureaucracy accidentally creates a whole subcategory of motorcycles.
Since CFMOTO already manufactures various levels of its other smaller sports bikes, with higher specification “SR-R” variants alongside the standard “SR” models, it makes sense that the same would apply to the 675SR. The near-finished version, recently presented in the colors of the Aspar racing team and fitted with exclusive track parts, was called the 675SR-R, which suggests that this name will be adopted by a high-specification variant. However, the bike in the new homologation, codenamed CF650-10, appears to be the base 675SR.
Compared to the 675SR-R, this variant does not have the extended side wings on the fairing and features a lower rear with a passenger seat and passenger footrests, as well as being complete with road accessories such as mirrors, a license plate holder and full lighting. This means we can see that the final bike’s turn indicators will be mounted on the rear-view mirrors, while the headlights, as expected, are hidden beneath the more prominent, swirl-shaped LED lights on the nose. However, the front brake cooling ducts seen on previous prototypes remain, feeding air to the four-piston J.Juan calipers.
Other specifications confirmed in the approval document include the exact capacity of the engine, 674 cc, and a code name of “372MT” for the engine. This name indicates three cylinders and an internal diameter of 72 mm. In turn, this means that the stroke should be around 55 mm, giving a slightly smaller bore and a longer stroke than the 675 cc three-cylinders made by brands such as Triumph (73 mm bore) and MV Agusta (79 mm bore).
