Again in 2020 we revealed Aprilia’s early designs for a tilting three-wheeled motorbike to rival Yamaha’s Niken and after greater than a 12 months of silence extra data on the undertaking has now emerged.
The unique designs confirmed a machine with a chunky-looking entrance finish design, utilizing forged alloy single-sided struts to assist every of the 2 entrance wheels. These have been mounted to a parallelogram-style tilting linkage on the prime—much like most three-wheelers together with the Niken—however had brief double-wishbone suspension items on the backside of every strut to hold the entrance wheels. Additional again, the design featured the rear body part, engine, and suspension from the 839cc V-twin Mana, full with its twist-and-go repeatedly variable transmission, even sharing the Mana’s rear bodywork.

That unique design is more likely to have represented a proof of idea, and little question a three-wheeled, Mana-based prototype lurks someplace in Aprilia’s Noale R&D heart, however it was by no means more likely to be indicative of the looks of a manufacturing mannequin. In spite of everything, the Mana isn’t in manufacturing anymore, and to revive its engine and bodywork for a distinct segment three-wheeled motorbike would have made little sense. Now a brand new set of patents exhibits that Aprilia has developed the thought additional, exhibiting an easier and extra compact entrance suspension association and ditching many of the carryover Mana parts seen within the first set of drawings.
The brand new design retains the parallelogram-style tilting geometry, one thing that Aprilia’s dad or mum firm Piaggio pioneered with the MP3 and which it has since fought mental property circumstances to guard, however ditches the thought of car-style wishbone suspension. As a substitute, every of the 2 entrance wheels is supported by a single, brief telescopic leg immediately above it, with scissor-style linkages between the higher and decrease sections to regulate the steering and cease the decrease half from rotating out of alignment. It’s a design not not like the only telescopic strut utilized by the crazy-looking Gilera CX 125 again within the early ‘90s. Gilera is, after all, a part of the identical Piaggio group of corporations as Aprilia.
Actually, Aprilia has filed patent functions for 2 variations of the system. One could be very very similar to the previous Gilera CX, with two sections to the scissor-style linkage that steers the entrance wheel. The opposite has only a single steering hyperlink to the decrease part of every strut, however provides a ball joint to the strut’s prime mount, permitting between 1 and three levels of motion because the suspension compresses. This structure kinds the principle a part of the most recent IP, with Aprilia claiming it provides helpful pro-dive conduct below braking.

Notably, the most recent designs now not present the Mana-based 839cc V-twin engine. Actually, they don’t present an engine in any respect, although the wire rear wheel and motorcycle-style chassis present that is nonetheless supposed to be a a lot higher-performance machine than the MP3. At the very least one picture does present a entrance sprocket cowl that appears much like the design used on Aprilia’s Tuono 660 and RS 660, and that parallel-twin, 100 hp engine would definitely be the obvious alternative from the agency’s present array of engines to make use of in a Yamaha Niken rival. It’s even doable—albeit unlikely—that the corporate may drop the 1,077cc V-4 from the Tuono V4 and RSV4 into such a motorbike, creating a unique proposition.
Whereas patents supply no certainty that an concept will attain manufacturing, it’s clear that is an concept that has been into consideration at Aprilia for a while. The most recent doc, whereas solely simply printed, was submitted again in October 2019; if improvement has continued since then, it won’t be too lengthy earlier than we formally see the outcomes of the agency’s work.
In the meantime, the one mass-made, leaning three-wheeled motorbike (versus scooter) in the marketplace—Yamaha’s Niken—can also be as a result of be uprated quickly. It’s the final surviving mannequin within the firm’s vary to make use of the unique, 847cc three-cylinder engine from the first-generation MT-09. Now, the MT-09 and its spinoffs have gained an nearly solely new 890cc triple, and the Niken’s previous engine resides on borrowed time in Europe, because it doesn’t meet the most recent Euro 5 emissions limits. As such, a second-generation Niken with the brand new 890cc engine and a redesigned body to match is believed to be on the playing cards for launch throughout the subsequent few months.
