Yamaha's Yard Built projects have led the way in the revival of the cool custom world. Developing relationships with the rock stars of motorcycle customising, the project has delivered an incredible line up of unique and breath-taking one-off Yard Builts based on the Sport Heritage range of motorcycles. Legendary customizers from across the globe have turned their skilled hands to proving how easy it is to customize one of Yamaha's very flexible retro machines. The exercise provides inspiration and has set new trends in the motorcycle world, making it a reality for everyone to make their Yamaha their own. 

XJR1300 ‘Botafogo-N’ by Numbnut Motorcycles

The 20th anniversary of the legendary XJR1300 continues with the third Yard Built production of the year, the first collaboration from Amsterdam based custom builders Numbnut Motorcycles.

The Dutch builders first Yard Built project is a visceral racing machine with road friendly manners, a fitting tribute indeed to the XJR.


Inspired by a one-off 1917 FIAT racing car, the 'Botafogo Special', the bike is an impressive custom machine built using a mix of in-house and aftermarket bolt-on parts with no cutting or welding to the original XJR frame. 

Satin black Boranni M-Ray wire wheels and Pirelli Phantom Sport tyres set the period tone, complemented by a Numbnut custom aluminium gas cap and custom made mesh side panels and rear underseat panel. A Numbnut 'Imola' custom front fairing with mesh headlight cover hides a state of the art LED headlight at the front, set off in stunning light green paintwork. 

At the front are Yamaha R1 forks and radial calipers and at the rear, Ohlins twin shocks. The racer look is further enhanced with Tygon 2375 clear brake reservoir hoses front and rear and all black Goodridge steel braided brake lines. A clever custom Numbnut primary socket cover lights up at the flick of a switch and Steel Dragon Performance aluminium velocity stacks and RF Biketech radiator provide some understated bling.

The dash gets a Stack ST200 tachometer, Sport Developments GP style control buttons and Biltwell grips on the bars. Power is delivered to the back wheel with a 520 RK racing chain wrapped around Chiaravalli sprockets front and rear. A screaming custom matt black 4 into 2 exhaust by MVS Race Engineering provides a suitably raw soundtrack. 

A host of in-house Numbnut custom parts finish the bike, including foot pegs, clutch and brake levers, heel guards, a custom alcantara seat by Eller Meyer and custom side and seat covers. 

A selection of the parts created by Numbnut Motorcycles are now available to order for XJR owners looking to personalise their own machines, adding to the options for customisation on offer from the Wrenchmonkees and itroCkS!bikes.
