Commissioned by BSA's USA distributor, the X-75 was designed by fairing specialist Craig Vetter ["cite book | last = Brown | first = Roland | title = Classic Motorcycles | publisher = Anness Publishing | date = 2002 | isbn = 1-84038-433-6 ] . Vetter built his design on the then newly released BSA Rocket3's 750cc three cylinder engine. It was ultimately released as a Triumph model in 1973 after BSA closed it's doors in late 1972. It had lowered gearing and a distinctive triple exhaust on the right-hand side.

Development

The Triumph Hurricane was developed in the summer of 1969 by Craig Vetter, the American motorcycle designer, who unveiled the prototype with "BSA" on the tank as the new ‘Rocket Three’ [ [http://www.craigvetter.com/pages/Motorcycle_Designs/Hurricane_Pages/Main%20Hurricane%20page.html Craig Vetter’s (designer) web site] ] .

The X-75 had a three US gallon petrol tank under the glass fibre bodywork and cost £895 new in the UK.

BSA was facing bankruptcy, however, so the design went into a limited production run of 1200 as the Triumph X-75 Hurricane in 1972. Production stopped in 1973 because the X-75 was not able to meet new American noise standards.

Surviving X-75's have a potentially fatal technical defect as cracks appear in either the top or bottom yoke if the pinch bolts are over-tightened. There was no specific torque setting issued by the factory for these pinch bolts. [ [http://www.realclassic.co.uk/hurricane05032400.html Real Classic Triumph Hurricane (accessed 2008-05-12)] ]
