It was the howl that stayed in the memory; a smooth,
high-pitched scream that ripped from twin mufflers as the Norton F1 rotary
motor hit 6000rpm and surged toward the redline with renewed thrust. The F1
distinctive exhaust note emphasized that this bike was different not only
from previous Nortons but also from ever)' other sportster ever built.
The launch of the F1 in 1990 was remarkable in itself. Norton's comeback had
begun a few years earlier with the release, after 15 years of rotary
development, of the Classic roadster.
The touring Commander followed, and
public interest in Norton snowballed when enthusiastic workers built an
alloy-framed rotary racer that won two national championships in 1989.
A roadgoing version was the obvious next step. The F1 was powered by a
Commander engine, turned back-to-front, fitted with Mikuni carburetors and
uprated with the five-speed gearbox from Yamaha's FZR1000. Enlarged ports
and revised timing helped lift output from 85 to 95bhp at 9500rpm. The
frame, built by local specialists Spondon Engineering, was similar to the
race bike's but stronger and had slightly more conservative steering
geometry. Dutch firm White Power provided the multi-adjustable upside-down
forks and shock. Brembo brakes and Michelin radials completed an up market
package.
Styling incorporated smooth bodywork that hid much of the
technology but left space for the cigarette-packet logos of race-team
sponsors JPS. Riding position was sporty, with wide clip-ons and a single
seat. The F1 power and weight figures were siniil; a typical Japanese
600, and so was its 145mph to the road, the rotary felt totally different,
though, smoothness, generous midrange punch and sp high-rev howl.
For a
sportster, the F1 was fairly c and its rigid frame and excellent
suspension g: surefooted handling. But there were rough edges; was thirsty,
its engine snatched at low revs and w overheating, and ground clearance was
poor. The hand-built F1 was also extremely expense lem Norton
addressed a year later with the slight F1 Sport, which used simpler bodywork
and lower parts. The Sport was a little less sleek and sophist like the F1,
it was quick, agile and distinctive.

The worlds only rotary-engined superbike was
hyper-expensive about US$45,000 back in the early 90s but went like blazes.
Unlike a conventional piston driven engine, the F1s 588cc, liquid-cooled rotary
engine had no reciprocating mass, and produced 95bhp@9500rpm in a smooth, linear
fashion. The Norton F1 RCW588 won the British F1 series in 1989, and the bike
was also raced in the Isle of Man TT races. The British Motorcycle Land Speed
Record was also set at 307km/h in 1991 using a Norton rotary engine. Steve Spray
and Trevor Nation were the two British riders who raced the F1 successfully in
various events in the UK.
As you would expect with an all-new engine design, Norton had various problems
with the F1's rotary engine, and the British company never really had the money
to sort those problems out completely. If only Norton had Honda's financial
muscle, the world of very fast motorcycles might have been a different place
today
