1965 Greeves 250cc Silverstone
Road Racing Model
At the start of the 1960s, the private owner
was reasonably well provided for with AJS, Matchless
and Norton machines in the Senior and Junior
classes, but in the lightweight category he
generally had to make do with a sleeved down
larger engine or a home-built special such as
the REG and Jones ohc twins. The other alternative
was to use a two stroke. This type got a boost
when Mike O'Rouke finished 7th in the 1960 Lightweight
with an Ariel Arrow and kindled an interest
in Cotton, DMW and Greeves.
The Greeves was to become the leading light
among British two-strokes during the 60s, the
first of the Silverstone models evolving from
a Villiers engined Sports Twin ridden by Reg
Everett in the Silverstone 1000 Km race for
production roadsters in May 1961. Thge production
racing machine was first marketed in March 1963
and had a very good season finishing with 4
out of the first 6 at Cadwell Park in September.
Substantially revised and with a new Greeves
engine replacing the old Villiers 36A unit,
the 1964 model RBS wasconsidered a worthwhile
improvement but was prone to high-speed misfire
and the new five-speed gearbox was a disaster.
Despite the faults, Gordon Keith won the Lightweight
Manx Grand Prix at 86.19 mphand his best lap
at 87.61 mph was the fastest time ever by a
British production 250.
The 1965 version, the model RCS, despite a
poor showing in the TT, came into its own again
in the Manx with another win by Dennis Crane
and Peter Williams in 3rd place. Out of 53 finishers,
13 were Greeves mounted.
The Silverstone line continued until the 1967
RES model but by now the Japenese opposition
with Yamaha and the Spanish Bultaco were outclassing
the Greeves and the factory concentrated its
competition energies on Motocross.
