Four-strokes for GP!
Two-stroke machines may still run, with a maximum fuel capacity of 32 litres. Four-strokes must have an engine displacement of under 990cc (500 for two-strokes in the premier class) and, initially, the four-strokes must be three-cylinders or more with a max fuel capacity of 24 litres for 2002-2003, then 22 litres from 2004. Three-cylinder bikes have a lower weight limit of 135 kilos; triples with oval cylinders (an obvious reference to Honda's dormant NR technology) plus conventional machines of four or five cylinders have a 145kg limit. For six-plus cylinders, the limit is 155kg. In a move that has caused some confusion, the FIM has left the door open for the possible two-cylinder four-stroke entrants, saying the issue is up for discussion and would be limited to genuine prototypes. Presumably this is to prevent entries of established superbike designs. How is this judged? Good question... McCOY DROPS TO THIRD IN 500cc CHAMPIONSHIP
McCoy finished only ninth on his Yamaha at the Suzuka track, where Japanese rider Norick Abe (pictured leading above) scored the third win of his 500cc career on another Yamaha ahead of American Kenny Roberts Junior on a Suzuki. The result was a little disappointing for McCoy after victory in the season-opener in South Africa and third place in Malaysia, but he was happy to grab another seven championship points. The relaxed 27-year-old from Camden, on the outskirts of Sydney, now has 48 championship points to the 55 of new leader Roberts, with the next round at Jerez in Spain on April 30. Spaniard Carlos Checa remains second on 51 points after gaining another 10 for fifth place in one of the best 500cc races for years with up to eight riders fighting for the lead mid-race. Even at the chequered flag the top eight were separated by just 4.9 seconds, but Italian Max Biaggi was a notable casualty on his Yamaha and reigning world champion Alex Criville of Spain blew his chances of winning by running wide into gravel soon after overtaking Abe and finished sixth. Australia's 250cc rider, teenager Anthony West from Queensland's Gold Coast, finished a fighting seventh in his race to maintain his fifth place in that championship despite still suffering a sore shoulder from a fall in Malaysia. McCoy went into the 500cc race as the world championship leader but found that cooler race-day weather quickly meant he could not maintain maximum grip with his 16.5-inch rear Michelin tyre. After qualifying 11th and briefly racing in eighth place McCoy settled in ninth until the finish of the 21-lap race. Displaying heaps of courage in front of his home crowd, Abe stormed past Roberts two laps from the finish to win, repeating his Japanese GP success of 1996. Factory Yamaha rider Abe elected to use a 16.5-inch rear Michelin tyre - but a slightly harder compound than McCoy - only after the morning warm-up session. Third-placed Tadayuki Okada of Japan also switched to a 16.5-inch rear tyre away from the traditional 17-inch on his Honda. McCoy had used the 16.5-inch style tyre in South Africa and Malaysia.
"My right hand, which I bumped in a practice crash on Saturday, feels a bit tight but it wasn't a big problem." McCoy's race engineer, Hamish Jameson, said: "We used Michelin's softest compound rear tyre and I guess Norick went a bit harder than us, but for Garry I don't think the tyre was soft enough. "It was perhaps a bit too cool for us - certainly cooler than the past two days of qualifying. "You never like to be beaten but we have to go away and learn from this, and perhaps also look at the set-up on the bike." In the 250cc race the Australian representative West rode well on his Honda to finish seventh after starting from 14th position. West made a blistering start and was seventh by the end of the first lap. "My bike behaved really well today," West said. "It was the best it's been all weekend. I got a good start and settled into seventh place. I had to up the pace at one time to keep it but I was still comfortable. It couldn't really be a better result for me seeing how I've been going in practice. "I'm still in fifth position in the championship so that is good." West's teammate Tohru Ukawa took second in front of his home crowd after an enthralling three-way battle with countrymen Shinya Nakano and Daijiro Katoh. Katoh scored his third win from his last three starts at Suzuka but Nakano still leads the 250cc championship. Japanese riders also filled all the podium positions in the 125cc race at Suzuka, with Youichi Ui victorious on a Derbi machine from Noboru Ueda and Masao Azuma on Hondas.

The existence of prototype machines in late stages of development was confirmed by the factory's head Euro test rider, Englishman David Bean, during 1998's world media launch of the R6 sportbike. Bean confirmed the system was being played with and may see light of day sooner than most people expected. The interesting part is that the system may debut on a road bike of some description rather than the off-road machine that most observers have expected. UK Motorcycle News reports what it calls a Yamaha insider as saying the system could be applied to scooters and large-capacity sports-tourers, as well as the obvious off-road machinery. Bean hinted that the road application had real benefits, while other sources mention greater stability, particularly in slippery conditions. This in fact may make scooters more appealing to people who are not bike-oriented if it gives them a greater feeling of security. UK MCN reveals Yamaha's Euro 2WD project leader as saying "We believe 2WD will open up huge possibilities for bikes now and in the future. If a designer has a clean sheet of paper, a bike fitted with 2WD could offer him a whole new set of options regarding where he puts the centre of gravity and how he designs the chassis." (You can visit MCN at www.motorcycleworld.co.uk) No firm release dates or models have been revealed at this stage, and it sounds as though Yamaha is testing the customer 'water' to see what the reaction is like before deciding on what configuration is released first. Various private designers and manufacturers have been toying with two-wheel-drive for solos over the decades, with Suzuki and Honda both reported to be working on their own systems. Australian engineer Ian Drysdale went one step further a few years ago by building a 2WD prototype with two-wheel-steering. The 2WD feature has been around for many years on limited production machinery, such as the American Rokon (www.rokon.com) - a robust off-roader that lays claim to having its variation on the theme on the market for 30 years.
