PATON S1-R LIGHT WEIGHT TRACK TEST
R I D E R E V I E W
P92
Strange to see a modern bike
with twin rear shocks, right?
the crank produced by the stock Kawasaki motor
there's an intermediate level of performance
for street versions of the S1-R, whose mildly
breathed on DOHC 180-degree motor
(one-up/one-down, piston-wise) produces 82 hp at
8500 rpm at the rear wheel. That's significantly more
than the stock Japanese engine, thanks mainly to
the exquisitely-made, freer-flowing SC Project
2-1 titanium exhaust.
But the kitted engine fitted to the test bike I rode
also benefitted from Pistal pistons lifting
the compression ratio to 12.5:1 from the
stock 11.3:1, together with some light im-
provements to the cylinder head aimed
at enhancing gas flow and combustion.
The ER6's twin 38mm throttle bodies
are retained with a single injector per
cylinder, together with the stock Kei-
hin ECU, but this is fitted with a Power
Commander to help get the best out of
the SC Project pipe. Torque is up signifi-
cantly, too, even with stock camshafts
fitted, with 64 lb-ft available at 7000 rpm.
(Left) The
streetbike will
deliver 82 hp,
whereas Dunlop's
racer will reach
a comparatively
massive 112 hp.
(Below) The
package is let
down somewhat
by the standard
Kawasaki dash.
