The
legendary RC30 was the proddy racers' version of the RVF750, which
trounced all the knackered old GSXRs and FZRs in the early '90s.
The Yam OW01 gave it a bit of a run for its money, spesh with Rob
McElnea aboard, but the RC was smaller, gruntier and handled better
in race trim. Fogarty was also smaller and gruntier.
Honda put some serious dosh into this little chap to win race
honours in the F1 and Superbikes, but the big wins were left to
the RVF750, a super-RC30 which cost a fortune. This bike was notorious
for the cost of the race carbs used in the TT races, £20,000
or some such mad figure was rumoured.
Beautifully
built, the RC30 has a major drawback as a roadbike. The excessive
heat given off by the engine escapes under the rear of the tank
and gives you superheated gonads. Supremely uncomfortable in the
summer - so much so that you dread having to slow down in towns.
Not so bad on the track but this heat spoils the bike for road use.
Apart from that the bike is a delight to ride. Engine is nice and
grunty for a 750 and has a unique viby V-four feel and sound, but
top-end is lacking compared to a modern GSXR750.
If
you start to give it serious stick the suspension shows its age
a bit and the weird wheel sizes limit tyre choice - 18" at
the back and a 17" x 3" at the front. Typical mod was
17" mags with a 3.5" front.
The carburation can be tricky to get right and isn't really helped
by a Dynojet kit. The problem is related to the airbox. The only
real solution is the factory airbox and carb mods. If you really
want to get your RC30 sorted look to spend £3000 plus on induction
and exhaust mods, plus some extra cooling to keep the engine temperature
under control. Race bikes had bigger radiators, but they cost a
fortune.

They go through hedges quite
well, as long as there isn't a
ditch in the middle!

Suspension is a bit basic and bearing in mind the odd size wheels
one starts to suspect that the road bike is a helluva long way from
it's racing cousin. 'Course, it wasn't that expensive at £8000
when it came out compared to the £12000 plus of the OW01-
the race kit for the RC included wheels and suspension kit as well
as engine tweaky bits.
Stuart got one just before an Isle of Man trip. Much excitement
at the prospect of sampling the bike at the spiritual home of the
RC30 but unfortunately the thing seized the week before we were
to leave and couldn't be repaired in time. Once it was repaired
it had a few Sunday outings but wound up in a ditch and the magic
was kinda gone ..
Some
years later, and another RC came up for grabs. A Spanish import,
but in good nick and six grand, so why not give it a go. Turned
up on a Sunday on it and everyone was hugely impressed that I'd
got a legendary RC30.
Due respect was shown for he who was obviously pretender to the
Pack Crown. Luckily I revelled in the brief adoration, for as soon
as we got started on the road everyone cleared off in short order
and left me droning along the roads in a very Hislop over the Mountain
sort of way, minus the speed. And the handling. Sports bikes had
moved on a bit and the RC was struggling.
Having scraped just about every bit of the bike and me on the road
trying to stay with the lads I determined that improvements would
be needed if this was to be a competitive outing. But after a few
more rides it became clear that the standard RC was not a good road
bike. Perhaps with lots of mods to the suspension and breathing
it may cut it, but why bother when a Blade will beat it at everything
for half the price? So I sold it and got a ... er, OW01.
In 1990 it was the best racer around once the factory kit was
fitted, but it was never designed to be a road bike so we're being
a bit unfair judging as such. But it serves to show just how much
modern production bikes have improved.
