Yamaha unleashes the Big Bad Wolf

Yamaha unleashes the Big Bad Wolf.

Yamaha has teamed up with Spanish customhouse El Solitario for the final XJR ‘Yard Built’  custom bike of 2015, celebrating 20 years of the iconic street machine.

The result is a race inspired track monster, the Big Bad Wolf, or BBW to its mates. The bike was introduced for the first time at the Glemseck 101 show in Germany and here’s a load of photos of it for you.

El Solitario’s Big Bad Wolf wraps up a year of incredible XJR builds celebrating the bike’s anniversary, a year that includes creations from Danish builders the Wrenchmonkees with the ‘Skullmonkee’, Portuguese builders itroCkS!bikes with the ‘CS-06 Dissident’ and Dutch builder Numbnut Motorcycles retro endurance racer inspired ‘Botafogo N’.

The BBW has almost everything custom made with the exception of the frame, the tank, the handlebars and the rear light, reducing the wet weight to just 183kg from the original’s 240kg.

Here is what Yamaha said about the build:

The Motor was blueprinted and the heads were ported and flowed. The intake port flow was increased by 50%. Compression was raised from 9.7-1 (Stock) to 10.7-1. The combustion chambers were reshaped & the squish areas increased. The rods were reinforced with titanium bolts and the crankshaft was rebalanced. All the electronics and were removed and state of the art Lectron 42 Carburetors were added, developed specifically for the BBW by Lectron Fuel Systems on their flow bench to be plug & play on delivery. A Dynatek Programmable Ignition was installed. The work takes the power up to 148 BHP at the rear wheel.

Classic Co. then fabricated a carbon fibre tail section, motor air rams and the belly pan, as well as all the aluminum brackets for the needed modifications. UK based Dymag developed the carbon fibre wheels especially to fit not just BBW but also the stock XJR1300. Acke Rising from ISR in Sweden did a lot of machining sing the El Solitario designs to make custom triple trees, disc rotors and the incredible rear brake caliper bracket. ISR hand controls were added along with ISR front 6 piston calipers and rear 4 pistons caliper.

K-Tech Suspension collaborated with Novatech to develop the impressive front forks and the rear shocks and the screaming custom titanium exhaust was made by Asahina Racing in Japan, designed to fit not just the BBW but the stock XJR1300 also. Moto GP oil cooler supplier, Taleo Racing in Madrid created the custom semi circular oil cooler and EMD in France, machined in aluminum the prototype motor covers which will be available to buy from El Solitario for the stock XJR1300 in the foundry version.

A TWM custom gas cap sets off the tank and a stunning custom aluminum swing arm by Over Racing in Japan finishes the rear along with a set of their rearsets. The BBW was wired using the Motogadget M-Unit & uses the M-Lock for on/off. Corona supplied the super cool quick shifter and PIAA supplied the intense headlights.

The BBW stays stuck to the tarmac with Michelin street, slick and rain tyres to maximize the fun whatever the conditions. Last but by no means least the beautiful custom graphics and paint was the work of London artist Death Spray Custom.
