Suzuki
GSXR750Y - getting better and
better |
|
Dunno
what he's doing looking at this 750Y as he's now a confirmed Honda
man again. Anyway, this Gixer was the first of 3 new Ys to arrive
on the scene for the Lobster Pot 200. We were going to split into
2 classes, one for all the Gixers and one for the bloke who hasn't
got a GSXR750, but then 2 got written off, Tet emigrated to Hondaland
and John got a 1000. But for a while 750s were the bike to have
while we waited for lighter 1000s
The bike is a good deal stronger from 6000 rpm than the X model
and you can actually get away with being one gear out, sometimes.
Handling is better all round than the earlier 750s, although the
bike retains the Grindley Peerless steering damper, fitted to increase
the bike's appeal to Triumph owners.
The Y really is a big improvement, turns better, holds a tighter
line and drives out harder.
Although ultimately not as abusable as an R6 or Gixer 600, the
new 750 feels more agile than a Fireblade or R1 when the road gets
twisty enough. So does the old one, come to that.

Sharp |
This
bike is SHARP, no doubt about it. We took it for a blast
through some nice twisty backroads plus a bit of A road stuff.
Getting off the WX and onto the WY and the immediate reaction
is "Jeez, this thing steers fast" - even with the poxy
standard steering damper on, and boy can you feel it on this bike.
Turn-in is now improved by Suzuki's reversion to a 5.5"
wide rear wheel fitted with a 180/55 tyre rather than the 6"
width of the WX wheel with its 190/50 fatty. Even shoving a 180/55
on the 6" rim only partially compensates as the tyre is spread
that bit wider, which doesn't do a lot for the profile.
But there's more at work here, for the whole chassis
seems more integrated and gives the bike a real flick-flick quality.
Obviously the decreased weight helps a bit, and the sharper front
end setup, and I guess it's the slight improvement in lots of
different areas that all adds up to a next generation feel.
Having
just replaced the back tyre on the WX and noted just how heavy
the sprocket carrier still is (it's the same design and weight
as the GSXR1100H!), we immediately spotted the complete redesign
of the WY's rear wheel and carrier - even though the X is light
there's a surprising amount of obvious weight saving to be made,
which Suzuki have concentrated on in the Y. So that's a new set
of WY wheels for my X please Suzuki ....
I thought the WX couldn't really get any better
- well it just did. It's the first time I've seen Wayne really
get excited about a new bike - and a 750 at that - and it's a
definite thumbs up from him, and a thumbs down for the WX!
I dunno, bikes are getting worse than computers; no sooner do
you buy the latest hot-poop tackle than they bleedin' update it
and make yours look like an old shed!

Tony's
Gixer is reborn |
|
Originally
intended just for track days, somehow Tony's Y has acquired headlights
and a number plate and re-emerged on the road. Perhaps the lure
of top class mates and breakfasts in exotic locations was too much
to resist any longer.
Now disporting robust fibreglass bodywork in track-day white, the
bike had to be roadified to gain access to the fabled Nurburgring
as well as the odd Sunday ride. Numerous mods have filled the long
dark winter evenings, although the bike has retained a businesslike
low-key appearance rather than the classic Christmas-tree Box Hill
look.
'Course, complete resistance to all shiny baubles was impossible,
and the faithful gold anodised back brake calliper had to be grafted
onto the bike, necessitating extraction of the swing-arm and extensive
modification to get it to fit - such is the price of decorative
perfection.
Other
goodies include knee-snapping high level rearsets for large lean
angles, AP front brake lever for super-pose and general loveliness,
PVM wheels for that "Oooh shit" feeling when you hit a
pot-hole in the road ('course, tracks don't have pot-holes ....),
Akrapovic exhaust system, which appears to have become de rigeur
for all bikes nowadays, and some fairing stickers for the true racer
look.
Big addition to the handling department is a Penske rear shock.
This is our first experience of the Yank shock, and it seems to
be very nicely built. Ride is firm but the shock gives good feedback,
so rear wheel slidey antics on muddy roads aren't at all scary.
Damping is good, and a bonus is the separate high and low speed
adjustment, so pothole damping can be tuned to perfection.
Front forks have been stuffed full of K-Tech internals by Simon
at Beckleys which has improved control over the already good standard
kit, so Chippy now has no excuse for not maintaining excessive corner
entry speeds.
The bike is now sporting the essential combination of Metzeler
and Pirelli race rubber for endless grip and big lean angles. Tony
has saved a fair bit of weight on the already light bike and it
proved to be the tool to have at the 'Ring ....
....
for a while, but it wasn't to last. A major slippage at Eschbach
meant a high speed stack into the armco, doing major damage to bike
and Tony alike.
Some weeks in Koblenz surrounded by needles and scary nurses cured
most of Tony, but the bike was beyond economic recovery and it went
off to trackday land.
So bye bye to a lot of hard work and not a little money and hello
to cars - Tony decided that enough was enough and four wheel slowness
and safety was needed.

Monday
8/5/00 - Thruxton track day |
|
This was a Steve Parish affair and very well organised.They have
made some alterations to the circuit since last year, a new tunnel
under the track instead of the gate operated by two old boys ...
I always thought that was a bit strange for a major racetrack ...
and they have resurfaced the whole track, even the pit lane! A great
improvement over last year. Most of the bumps have gone and the
surface is now very grippy indeedy.
We
signed on, bacon rolls and coffee were served, a quick talk on safety
and then out on the track.
We were the first on and from the start the GSXR750Y felt very
good ... the bike is so light, you notice it straight away, and
the noise of the induction its louder than the exhaust! It steers
quickly and pulls strongly - yes it's got a midrange, wonderful!
On the road the handling I thought a tad hard over really bumpy
stuff but I guess that's the price you pay for racebike handling.
Before
I knew it I was behind Sean Emmett on the new Honda VTR SP1. I followed
him for a couple of laps and realised that the GSXR is obviously
designed for serious track use. Handling is definitely better since
I dropped the forks about 7mm through the yokes and seems to have
settled the front and allowed the bike to hold a tighter line.
Lunch was a full-on three course affair, luxury stuff, then back
to the fun. After one more session we had to get fuel which was
only 3 miles down the road, which is handy. By this time people
were getting braver and it was starting to get a bit more interesting,
seeing if I could keep with R1s ZX9s and so on - no problem at all
as the Y's extra little bit of poke really makes a difference on
the track and it is so good through the bends that it was easy to
tuck up inside bigger bikes and pass them mid corner. The only problem
was R1s would sometimes whack past me on the straight.
Generally a brilliant day and not one crash! 'Course it rained
all the way home and it took me 4 hours to clean the bike .. that's
the only problem with new bikes, you feel you really ought to keep
them shiny. Mark
Some times laters ....
Well, after all the enthusiasm for the new Gixer things look a
little sadder now. Tony wrote his off (not his fault he maintains,
"I was taken from the rear", but is this relevant?), and
then wrote it off again and parts of himself with it at the 'Ring,
Mark's has been written off by a twat who nearly wrote Mark off
as well when he rode into the side of him, Tetley decided that the
Gixer has the build quality of a plastic spoon and got rid of his
for a Honda Fartyblade, John chopped his in for a GSXR1000 and Keith
succumbed to the charms of an R1 ...but the Gixer will return!
