The shock (for me at least) of today’s Bonham’s’ sale was this, MZ's 250cc Grand Prix racer in its ultimate form: estimated at £3500-£5500 the eventual buyer paid a whopping £35,650. Suddenly eastern European race bikes are in the news, not least I’d guess because Mat Oxley’s fabulous book Stealing Speed looks likely to make it onto the silver screen.
Introduced in 1955, the first MZ 250 racer - effectively a doubled-up 125 - was air-cooled and fitted with a four-speed transmission. Maximum power was 25bhp at 8,000rpm. Water-cooling was adopted in 1962 on the RE250, boosting power to 48bhp at 11,000rpm. By 1970 a six-speed gearbox was standard, and with 50-53 horsepower on tap the RE250 was good for a top speed of 140mph. Silvio Grassetti rode one to a win in 1971 as well as a couple of runner up spots before the factory's racing effort folded in 1977, when all the existing bikes and parts were sold off to privateers.
This ex-works example formed part of the Warrick Blackwell Collection since at least 1992 and has been displayed at both the International Classic Bike Show and Midland Classic Bike Show. Sadly, nothing is known of its in-period racing history. Accompanying history includes photocopied marque-related literature; a selection of photographs; and an invoice/letter from John Mossey dating from November 1992 in which he states that "the bike starts good and runs up a treat and sounds sharp and clean on both cylinders".
MZ authority Manfred Woll advised that the front fork is from a 1977-onwards production roadster, while the rear suspension struts have been modified to a later specification. The covers for the expansion chambers are also incorrect. Otherwise the machine is believed to be as it should be, and a minor backwater in the history of 250GPs. Until today’s sale – proof that if you get the knowledge out to prospective buyers wallets get opened in remarkable ways
