LONDON.- Bonhams are to sell a truly unique motorcycle which has spectacularly covered over 1million kilometres at the hands of one careful owner. It will be auctioned at the International Motorcycle Show in Staffordshire on April 24th 2011 and has attracted a pre-sale estimate of £35,000 – £40,000.

Northumbrian born Vincent enthusiast Stuart Jenkinson bought his new 998cc Black Prince from St. Andrew’s Motors in Newcastle-upon-Tyne in 1955.

For 25 years Stuart used Vinnylonglegs for riding to work and long distance touring holiday
