The SP-1 is good,
and set to get better
By Richard Fairbairn and
Kei Nashimoto
HONDA?S all-new SP-1 is as sweet-handling as a
250 GP bike, as torquey as an RC45 World Superbike
and so rider-friendly you can crack the throttle
open mid-corner with little fear of it spitting you
off.
But this isn?t the
verdict of Honda?s top riders, Aaron Slight and
Colin Edwards, who are contracted not to say a bad
word against the firm.
No, that?s the verdict of
one of the first independent testers to ride the
1000cc V-twin.
Japanese domestic series
superbike rider Kei Nashimoto who, like Slight and
Edwards rode a RC45 this year, is also a journalist,
and he?s given us a fascinating insight into the
most eagerly awaited bike of 2000 after he rode one
in Japan last week.
Nashimoto?s comments
coincide with recent Honda tests at Phillip Island
in Australia, where Slight and Edwards put a revised
version of the bike they will use in WSB next year
through its paces. It features a host of changes
over the "stock" bike which will used by
every team other than Castrol Honda. But even in its
standard trim, Nashimoto said the SP-1 is already
way ahead of the RC45, especially in the handling
department and at giving feedback from the front
tyre.
He said: "What
surprised me most about the SP-1 is how light it
feels compared to a four-cylinder machine, despite
being the same weight (Honda is still in the process
of cutting weight).
"The whole chassis is
so well balanced that it handles like a 250 GP bike.
It?s more comfortable to ride than the RC45, and
even on my first time out I felt completely at home.
"The SP-1 is totally
dependent on the front tyre when it comes to
cornering. It feels like a very
"front-end" type of bike. This means that
it turns very sharply and naturally, almost without
any effort from the rider. Some people won?t like
this, but I think it is very positive.
"This also means you
get a large amount of feedback, which was very
helpful for me when I rode in the wet. It actually
made riding in the rain fun, because it was so
confidence-inspiring. The Showa suspension fitted to
the bike I rode wasn?t as good as the set-up which
will be used on the factory racers, but it still
gave me a lot of information about what was
happening under the tyres."
Nashimoto is also one of
the few men on the planet who can compare the new
VTR1000 SP-1 with a race-spec version of the
FireStorm.
He said: "I rode a VTR
built just for racing by Moriwaki, and I can tell
you the new bike is in a different league. The
FireStorm had a very harsh throttle response which
was sometimes too abrupt to handle, but the SP-1 is
nothing like that. The fuel injection system is very
smooth and you don?t get any of the sharp pitching
forwards and backwards when you open and shut the
throttle like you did on the old VTR.
"It means there?s
little to fear when you open the throttle. You know
the back tyre wants to push you forwards, not snap
sideways. The bike feels very torquey compared to
four-cylinder bikes, so when you open the throttle
at low revs it really wants to accelerate. There is
no delay in acceleration waiting for revs to rise
like there would be on a four."
Though Nashimoto says
it?s a big improvement over the RC45, he still
thinks it could be better.
He said: "There are
negative aspects to the new bike. Because it?s a
twin, it feels like it runs out of power much
earlier than a four. The initial huge surge of
acceleration tails off as the revs rise. Also, the
clutch is not so good. It feels like it has far too
much play in it, and it feels a little vague under
engine braking. This needs to be modified because
the engine braking is far stronger than on a four.
Even if this was a road bike, the clutch would feel
bad. But these are minor faults and I think the VTR
will be very competitive against the fours."
Slight and Edwards? bikes
are likely to have more power because they will be
in a higher state of tune. Their bikes will also get
power-boosting and weight-reducing parts from the
factory before any other team, and many of these are
still being developed. A Honda spokesman said:
"The test went well, but there is still a lot
to do. We are working hard to get more power from
the bike, and also to cut weight. It is about 4kg
over the 162kg limit right now."
Nashimoto?s assessment
will be music to Honda?s ears. This is the machine
which will race in Britain next year, as well as
many of the other domestic superbike championships.
But that hasn?t stopped
HRC, the racing arm of the factory, changing several
aspects of the bike to ensure it?s more than a
match for Ducati?s dominant 996 in the world
series.
The bike has already been
fitted with an all-new exhaust system which sees
both pipes exit on the right. On the standard bike,
there?s a can on either side. The exhaust has been
swopped to allow the fitment of a different
swingarm, which appears far more substantial than
the one it replaces.
HRC has also ditched the
Brembo brake calipers which are fitted to the
standard SP-1 in favour of six-piston Nissin items
identical to those used by Yamaha rider Noriyuki
Haga. Both Edwards and Slight didn?t get on with
Brembos last season.
The brakes are attached to
47mm Showa forks, which are heavily revised
internally from those which will be use on the
British superbikes, as is the rear shock and the
linkage. This has been done as much out of
Edwards? and Slight?s personal preferences as
anything else.
Edwards? best time at the
test was an impressive 1:33.6, just 0.6s outside
Troy Corser?s lap record from this year?s
Australian WSB round, despite the surface being
dusty and lacking in grip. It was also nearly a
second quicker than his best time in early tests of
the bike at the same track last year. Edwards
crashed twice because of the conditions, but escaped
injury. Slight was marginally slower.
The pair were also able to
compare how fast their bikes were next to some of
the machines they?ll line up against next season.
Haga was also at Phillip Island, and his R7 was
faster than the Honda.
This shows just how
different the V-twin SP-1 is from the old V4 RC45,
and how Edwards and Slight will have to ride it
differently. From riding a bike which was regularly
the fastest in a straight line but not the quickest
on lap times, the pair now have a bike which may
lack outright top speed, but puts in fast laps -
like Ducati?s 996. If during the winter Honda can
get more than the 170bhp which the bike is said to
be making at the crank now, Ducati should start
worrying.
