Honda patent reveals radical superbike plan

The new, highly detailed patent drawings show that Honda is deeply involved in the development of the Street Legal Superbike. (Patent Office /)

It’s been 30 years since Honda changed the establishment of Superbike from the front Launch of CBR900RR Fire BladeHowever, the era of the company’s dominance in the Superbike segment is long in the past. Now, the newly revealed patent shows how Honda plans to counterattack with a convention busting design that aims for radical weight loss compared to its current rival crops. increase.

Fireblade has changed the world of superbikes, ignoring race capacity regulations and becoming a road-only bike that combines a 1,000cc power level with a 750cc class weight. It was a combination of rivals that followed quickly, with the 750 class eventually disappearing altogether, and Honda rarely surpassing it ever since. Since 2007, the company hasn’t led riders to the title of the Superbike World Championship or won the maker championship in the series since 1997. RC45..

One of the drawings is a horizontal 4-cylinder engine used as a structural member of the frame, with a part of the chassis bolted to the case.

The new designs that appear in Japanese patent documents are unusual in some respects. Besides choosing unusual structures and materials, the patent itself is very detailed. This includes radical chassis descriptions and drawings, equipment, mirrors, bar controls, and auxiliary components such as sidestands and catalytic converters. It’s all confirmed to be a road-going machine with production in mind, not just a racer or just a concept bike.

The frame is the main deviation from the standard. Instead of the usual aluminum beam chassis, a transverse 4-cylinder engine forms the main part of the structure. It’s not unusual in itself, Ducati Panigale V4 When Aprilia RS660 Using a partial frame with the engine as the main structural member, the Fireblade itself was equipped with a structural engine in 2000. CBR929RR Versions Introduced — The versions shown in Honda’s new patents are more radical than most versions.

Its front chassis piece incorporates an airbox and also includes space for electronic components.

There is a front chassis section that is described as “cast material”, and therefore probably made of alloy, to hold the steering head. It is bolted to the engine case and forms an inverted U shape over the cylinder and cylinder head. Ducati Panigale 1199The monocoque chassis incorporates an air box and air cleaner. In the hollow front section of the frame, just behind the steering head, there is a space filled with electronic components such as the bike battery (marked “110” in the drawing).

Similar to the front frame section, there are a pair of small cast frame halves on the back (18), one bolted to both sides of the transmission case to provide additional strength to the swingarm pivot. The swingarm itself looks like a one-sided design, but the patent text doesn’t clearly explain it, but the documentation states that the side stand can be bolted directly to the crankcase or extension of the rear frame section of the engine. It has been.

Unusual design elements include seats and fuel tanks combined with a self-supporting one-piece unit.

It’s the seat unit and fuel tank that actually move the bike away from the norm. These are combined into one. The entire unit (marked “17” in the drawing) is a self-contained, integrated carbon fiber component bolted to the front frame section, with a monocoque design and an outer skin that doubles as a structure. There is no rear “bodywork” itself, there is a seat above the subframe / fuel tank moldings, and the rear lights and license plate hangers extend from behind.

Therefore, the bodywork of the bike is only the front and consists of 4 sections. In addition to the two side panels (31) and berry pan (32), there is a nose labeled “30”. The patent also describes how the side stand is set in the berry pan when stowed. This is a design that is reminiscent of past Honda such as NR750 and NS400R.

You'll see the details of the instrument panel, from reading the tachometer to controlling the bar.

The instrument drawings and descriptions have even more amazing details. The patent explicitly states that there is an analog tachometer on the left side of the display that reads up to 14,000 rpm, and the entire right side (marked “50B” in the drawing) is a speed LCD multifunctional readout. increase. And other information. There is also the detail that the clutch is hydraulic, and the brake and clutch master cylinder reservoirs are engraved to fit the bike design. There’s no doubt that you’ll see more details about the bike’s bar controls, and the pod on the left has additional buttons that give you access to dashboard menus and settings.

Despite some unique design sketches, other signs show an unchanged 4-cylinder power plant with stock brakes and suspension as well.

Combining all these details with a traditional-looking 4-cylinder engine that looks much like the current Fireblade, and resolutely regular forks, brakes and rear suspension, this bike is a more viable production than the rare one. The structure and styling of the chassis may suggest that it is a prospect. The patent clarifies that weight loss is the goal, but also includes references to reducing manufacturing costs. This again suggests that this is more than just a lazy engineering exercise. Does Honda have plans to repeat the first Fireblade market-disrupting launch in more than 30 years?

Since the actual bodywork does not hang on the single seat / tank unit, all panels are visible in the foreground and are divided into four elements, including the nose.
