1971 AJS 250 STORMER
WHAT THEY COST
Recently, a still-crated Stormer sold for $10,000.
Unfortunately, even nicely restored AJS’ seldom sell for
more than the cost of a quality restoration, which is about
The 250cc Stormer (Y4), the 370cc Stormer (Y5) and, in
1973, the 410cc Stormer.
WHAT TO LOOK FOR
As with all collector bikes, try to find an AJS that is as
close to original as possible. You want the standard Girling
shocks, gel-coat orange or yellow tank, Reynolds chain,
and, if it has the original Dunlop Sports tires in like-new
condition, the tires themselves are worth about a grand.
AJS Motorcycles owner Fluff Brown claims to be able to
supply about any part needed to rebuild a Stormer. E-mail

rapidly aging 250cc Villiers Starmaker engines by pairing
them with a legendary motorcycle name. While the
antiquated engine held the Stormer back, the chassis was
a revelation (for the time), as it was the first motocross
bike to feature leading-axle forks and moved-up shocks. It
also had eccentric chain adjuster and a cross-over pipe.
The Stormer 250 (designated Y4) had some racing
success in the British 250cc Championships, as factory
rider Malcolm Davis won the championship in 1968 and
1969, and his teammate Andy Roberson finished in
second. Unfortunately, soon after the Stormer started
selling in the American motocross market, Suzuki
introduced the TM250 and TM400, and Yamaha introduced the DT-1 MX and RT-1 MX. The Japanese bikes
were much cheaper (starting at $950 compared to the
AJS at $1245), and by 1974 (and for years afterward)
consumers could purchase brand-new AJS Stormers, in
the crate, for $600. ❏
