RACER TEST ty I'm not sure a rider could ever really get used to ·it. You'd have to be very brave to tell yourself 'I've got traction . control' and keep the throttle wound wide open all the time! When tires start smoking up on TV, there's not a lot of traction control on view, and that all adds to the spectacle and hopefully is one of my strong points." 50 does Mick short-shift all through the gearbox to 'keep riding the power curve? "Well, what I call short-shifting would only be 1000 revs off normal changing up at eleven-five instead of around 12,500 rpm, as usual. In higher gears like fourth and fifth,. I'll take it higher, and try to rev it through to about 13,000, so it carries the gear higher. I don't hold a gear so much as other Honda riders do, though - but most of them grew up in the 125 and 250 class, where you have to rev 'ern right out. I'll upshift, then backshift - but I have been known to rev it as high as 14,000, but by then you're well and truly out of the power. That's why I told you off a couple of years ago for overrevving it there's no paint doing it, becauS!'! it's not making any power up t]jere, and on a straight you're just losing time doing that. Twelve thousand five hundred to 12,800 is a good shift area - but if you're in, say, a third-gear turn and you're geared to 66 feet from the apex, 1 guess it's easier to hold the gear and rev the bike, or if there's a kink in a straight section and you roll on and off the side of the tires and the revs rise and fall - that's what the overrev is for. It's safe power up there, though, because it hasn't got (Above) You want power? The NSR now delivers roughly 400 horsepower per liter from its SOOcc V-four. (Left) Costly Mitsubishi carbonfiber discs and Brembo calipers are the best - ever. enough to break the rear wheel away, and if it does, it's got nowhere to go. Do the same thing 3000 rpm lower down, and you're going to be flyi.ng pretty high." A constant reminder of Doohan's terrible '92 injury is a locked-solid right ankle which in turn resulted in the famous thumb-brake for the rear wheel, developed from a personal watercraft throttle and since copied by many other And the .ractical exam... O 14 kay, first the theory - now the practice. Time to put the lessons of Mick's master class into effect. Only one prob. Jem: I had just five laps to do it in, on an Eastern Creek circuit 1'd seen for the first time that morning. Back to basics. No greater test of the NSR500's chameleon character could be made than to use it for course learning, in preparation for my day's other duties - track testing the new breed of V-twin Honda GP bikes. Bit of an insult, though. Rather like using Damon Hill's world champion F-I Williams to run to the market. It's a mark of how brilliant a piece of empirical development the decade-old NSR500 design is that, while you certainly couldn't think of driving the Williams anywhere furthet offtrack than the Silverstone parking lot, the Honda would make a phenomenal road bike - just so long as you never took it more than two-thirds of the way to its redline, and never out of third gear. Oh, yes - and you'd need to find somewhere to mount the license plate, Wobbling around my first lap of the Eastern Creek infield in second gear, course-learning in company with Australian Motorcycle News editor Ken Wootton on Mick's identical spare bike, underlined what a pussycat of a panther the NSR500 is - SO long as you have the throttle no more.than hali-open. After one lap of course-learning almost under my wheels it was time to gas it up hard down the long front straight, with that wicked left-hand kink just past the pits, Ohmigawd. Dr, Jekyll quickly becomes Mr. Hyde. Cranked over around the long left leading onto the straight, gradually feeding in the power as the track opens up, the Honda that pulled cleanly and smoothly out of hairpin turns from as low as 6000 rpm started to change personality as soon as the tacho needle hit nine grand. Five hundred rpm later, it just took off. The -engine starts to accelerate very quickly from there on up, switching into interplanetary mode from 10,500 rpm when your view of the world around. you goes into overdrive, The front wheel pops up in third gear while you're still slightly cranked over, the engine note hardens as the revs mount, the wind batters your body as you try manfully to struggle down behind the screen while still more or less pointing this missile in the right direction, and you shift up through the gear.; on the still swprisingly mechanical-feeling shift action - remembering to back off the throttle slightly each time, rather than keep it gassed wide open like on other makes of bike. • perfectly fit riders, including teammate Alex Criville and the new World 5uperbike champion, fellow Aussie Troy Corser. Is this such a smart piece of kit 1 need to practice getting used to using it? Mick smiles. "1 need the back brake on the way into a turn because if I just use the front, it means the front suspension's loaded all the way in, so there's more chance of it pushing and unloading the tire," he Then. suddenly, it's time to think about backing off a little, even by my novice speeds, for turn one, then getting hard on the brakes and zipping down through the gears for the tum-two hairpin - taking only a moment of glee to imagine the consternation on the faces of HRC bosses as Wootton and I zapped past the pits together, dre and ripples left by cars at the Creek, even as compacted as they can be under hard braking. Brilliant. In tum, thi means that the geometry of the bike stays pretty constant, especially with my half-hearted attempts to put Mick's words into practice and use the back brake hard to make the bike sit better in the -tum. HRC had fitted a foot brake as well as the thumb one for us joumos, and I concentrated on using that. The result is you pick a line in a tum, and the Honda hugs it easily, riding the bumps SO effortlessly while waiting for the big moment when you're ready to get back on the power and - hold on tight, here we go again! If Doc Doohan - or is that Sir? - reckons the power transition is something to worry about on the V-four, that just underlines why he's a three-time World Champion bidding for a fourth: he's not easily satisfied. Ninety-nine percent of other racers would give anything to have the Honda engine's sweet pickup and smooth but so powerful response. But not The Boss. I mean, I can see how everything happens very fast from 10 grand upward, but that's surely a function of just how much sheer horsepower there is at your disposal. True, spreading out the rev range over which it's delivered would be nice for novices like me, to make everything happen a little less violent- says. "Basically, I use the front brakes to stop the thing and the rear one to keep it balanced, and make sure it handles properly and the forks keep working. But you have to use the front brakes first, or el e the rear end starts locking up and hopping. But then if I've got one finger on the rear brake just as I'm starting to stop, I'll be pleased. "But then on the transi tion into the comer, I'll be starting to load the rear up quite a bit, to get th~ whole bike squatting nicely into the apex instead of going in with the tail in the air and the back end all light. That way, the all-important transition from on the brakes to off them and hard on the throttle we've been working so much on this season will be improved, imd you'll come out of the comer quicker and faster." ly, but that's not what Mick's seeking. He just w~ts that little stutter when you go from a mostly closed throttle to a mainly open one smoothed away. r d be happy if my bikes carbureted like half as well as that, thanks - just so long as I had that amount of power as the end result. Awesome. And very, very physical. rust five laps of Eastern Creek, the fastest of them over 10 secOl;lds off Mick's best race time the day before, had me searching for breath, puffed with the effort of trying to keep the HOllda pointed in more or less a straight line with the pOwer in five-figure mode. Riding a works 500 at any sort of speed on a track like Eastern Creek which is better suited to 125s - okay, maybe 2505 - is an intensely demanding experience in terms of concentration as well as phy
