Spanish aftermarket manufacturer Puig has unveiled its new Diablo concept bike, a wildly styled take on the latest-generation Yamaha MT-09, that it says previews the future of custom motorcycle design.
The Puig Diablo builds on the range-topping Yamaha MT-09SP naked bike that launched early last year, with advanced wind-tunnel-tested bodywork that incorporates active aero elements, and racier track-bike ergonomics.
Said bodywork uses an electronically controlled windscreen and side-fairings that adjust to improve downforce and engine cooling as necessary. The Puig Diablo’s aerodynamic features also extend to a sporty rear cowl, a sharp nose piece and disc brake covers, among other bespoke parts.
Befitting the futuristic theme is a (possibly non-functional) transparent dash unit and striking LED lighting arrangement.
While Puig has not revealed plans to put a Diablo kit into production, the development of the concept is said to be its take on the future of custom motorcycles and accessories.
“We wanted to open the debate on what the motorcycle and accessories of the future can be like, showing how we imagine it at Puig and the result, the Diablo,” said main designer Miquel Vallribera.
“I think [the Diablo] is the perfect exponent, with active aerodynamics, protection, functionality, and aesthetics as designing principles”.
The Puig Diablo benefits from performance upgrades like lightweight wheels, a full exhaust system and upgraded suspension, however, it appears to carry over the Yamaha MT-09’s standard 87.5kW/93Nm 889cc triple-cylinder engine.
The current Yamaha MT-09 range is available from $15,699 rideaway for the base variant, or $18,099 for the higher-spec SP grade that adds a fully adjustable KYB front fork, while an Ohlins shock absorber allows for compression and damping adjustment at the rear.
In 2021, the Yamaha MT-09 received a significant update that included a stronger six-axis rider-assistance suite borrowed from the YZF-R1 sportsbike.
The enhanced rider aids see three-level traction control, slide control, front wheel lift control and brake control as standard.
Also new is a 3.5-inch TFT display with a bar-type tacho, while an up/down quickshifter is standard and braking is enhanced by a new radial front brake master cylinder.
