All new Honda is preparing new sports bike four-cylinder design is a blend of carbon and cast alloy. It's been 30 years since Honda turned the superbike establishment on its head with the launch of the CBR900RR Fireblade, but its era of dominance in the segment is over. According to a newly revealed patent, Honda may plan to fight back with a radical weight-loss design that will challenge the current crop of rivals.


The Fireblade changed the superbike world, ignoring racing regulations for a road-only bike with 1,000cc power and 750cc weight. Honda has rarely topped the class since then, and rivals soon followed, eventually leading to the abolition of the 750 class altogether. The firm hasn't taken a rider to a World Superbike title since 2007 or won a manufacturers' championship since 1997 and the era of the RC45.

In several ways, the new design, which has appeared in Japanese patent documents, is unusual. As well as its unusual construction and materials, the patent’s description and drawings of the radical chassis and even the sidestand and catalytic converter confirm that it was designed as a road-going machine rather than just a concept bike or racer.


The frame is the main deviation from the norm. Instead of the usual aluminum beam chassis, the main part of the structure is the transverse four-cylinder engine. Although bikes like the Ducati Panigale V4 and Aprilia RS 660 use partial frames as main structural members, and the Fireblade toyed with the concept in 2000 when it was introduced in CBR929RR form, Honda's new patent is more radical than most.

The front chassis section holds the steering head, described as being made of a "cast material". Unlike the Ducati Panigale 1199′s monocoque chassis, it incorporates the airbox and air cleaner. It's bolted to the engine cases, forming an inverted U shape over the cylinders and cylinder head. Just behind the steering head, there's a hollow space (marked "110" on the drawings) that's filled with electronic components, including the bike's battery.


Along with the front frame section, there are two small cast frame halves at the rear (18), one bolted to each side of the transmission case to support the swingarm pivot. Despite not being explicitly stated in the patent's text, it appears the swingarm is a single-sided design, while the sidestand could be bolted either directly to the engine's crankcase or to an extension of the rear frame.

This bike really stands out from the norm in its seat unit and fuel tank, which are combined into one. The entire unit is a one-piece carbon fiber component, bolted to the front frame section. Made of a monocoque design, the outer skin doubles as the structure. It doesn't have a rear "body" per se, just a seat atop the subframe/fuel tank molding, with a rear light and license plate hanger.


As such the bike’s bodywork is only at the front, and is made of four sections. There’s a nose—labeled “30″—along with two side panels (31) and a bellypan (32). The patent even goes as far as describing how the sidestand is set into the bellypan when retracted, a design that’s reminiscent of past Hondas including the NR750 and the NS400R.

There’s even more surprising detail in the drawings and descriptions of the instruments. The patent shows, and explicitly states, that there’s an analog tachometer on the left of the display, reading to 14,000 rpm, and the whole right-hand side (marked “50B” in the drawings) is a liquid-crystal multifunction readout for speed and other information. There are even detailed specifics about the clutch being hydraulic, with the reservoirs for the brake and clutch master cylinders being sculpted to suit the bike’s design. Yet more detail is on view in terms of the bike’s bar controls, with the left-hand pod featuring additional buttons, no doubt to give access to menus and settings on the dash.


All these details, along with the conventional-looking four-cylinder engine, which appears largely similar to the current Fireblade’s, and resolutely normal fork, brakes, and rear suspension, combine to hint that this bike is a more viable production prospect than the unusual chassis construction and styling might suggest. The patent makes clear that weight loss is the target, but also includes references to reducing manufacturing costs, which again hints that this is more than just an idle engineering exercise. Could Honda have plans to repeat the original Fireblade’s market-disrupting launch more than 30 years later?
