Superbike World Championship
Round 2: Kyalami (South Africa) - April 1st 2001

Michelin frequently competitive at Kyalami
From the six Superbike World Championship races that Kyalami has hosted, Michelin has claimed three wins: in 1998 with Pierfransco Chili (Ducati-Michelin), in 1999 with Carl Fogarty (Ducati-Michelin) and last year with Colin Edwards (Castrol Honda-Michelin).

Making its SBK debut in South Africa in the hands of Colin Edwards, the Castrol Honda VTR 1000 SPW-Michelin won the 2000 season's curtain-raiser at Kyalami. The American rider, who made maximum use of his 16_" front tyre, performed a memorable outbraking in the final lap to take the laurels for Honda's new two-cyclinder bike. Not long afterwards, the VTR 1000 SPW was back in the motorcycling headlines when it won the celebrated Le Mans 24 Hours. The common demoninator between the two successes was of course that both were achieved on Michelin tyres.

Three of the four fastest riders at Valencia
The opening round of the 2001 championship at Valencia (Spain) on March 11th saw three Michelin runners amongst the weekend's four fastest riders. Over the course of the three days of practice and racing, Troy Corser (Aprilia Axo) was the fastest man on the track with a lap of 1m 35s504, but he was closely tailed by Ruben Xaus (Ducati Infostrada-Michelin) with a time of 1m 35s830, Ruben's teammate Troy Bayliss (Ducati Infostrada-Michelin) on 1m 35s957 and Tadayuki Okada (Castrol Honda-Michelin) who set a lap of 1m 36s086. These performances take on added significance when you realise that Valencia was the first ever Superbike World Championship outing for both Xaus and Okada.

Troy Bayliss finished each of the meeting's two races in second position to move into second place in the provisional championship standings. "The bike was excellent and my Michelins worked very well," said the Australian. "I am quite happy with the result. It was a positive weekend and I feel much stronger than last year. The championship is long and it will be important to score vital points to be able to fight for the title."

</pre> Bayliss pleased with winter testing at Kyalami
The official International SBK tests organised at Kyalami on January 29th/30th/31st and on February 1st saw Troy Bayliss put in an excellent second fastest time behind Neil Hodgson (Ducati GSE Racing): "I am really pleased with the race simulation we did," said Troy Bayliss. "It confirmed the excellent quality of the material we were testing and I felt really good on the bike. I kept up a good pace with times that were lower than the best laps in last year's race. These results demonstrate that everyone has worked really well. Michelin gave us some excellent tyres, both for the race and qualifying, and this was demonstrated by the time I set."

</pre> Kyalami and tyres
Inaugurated in 1961, Kyalami hosted its first F1 Grand Prix in 1967. The track was modified in 1987, then again in 1991. Circuit length is 4.263 km, while its width at its narrowest part is 13 metres. The profile is very undulating with a large number of climbs and descents (steepest incline: 8.8%). The start-finish straight is 470 metres long.

The South African venue is located at an altitude of 1,500 metres, and the thin air is of course counter-productive to engine performlance. But the main feature of this track is its big variety of corners, ranging from slow speed turns with a radius of 15 metres to the fastest corner which has a radius of 162.485 metres. Meanwhile, many corners have a marked camber which, added to the circuit's hilly profile, makes Kyalami extremely challenging.

"Kyalami is a circuit that doesn't really have any outstanding features, unlike venues such as Welkom, where Garry MacCoy (Yamaha Red Bull-Michelin) won last year's 500cc Grand Prix, and Phillip Island where the next round of the 2001 Superike World Championship will be held. Tyre wear at Kyalami is symmetrical," explains Michelin's Superbike programme Manager Jean Hérissé.

"During our winter tests here we had an equation with two unknowns to resolve because of track changes and evolutions to the bikes. Honda, for example, has replaced the RC 45 with the VTR 1000 SPW. Happily, we were able to get in a lot of laps in the January test session which was very positive for the development of both our race and qualifying tyres."

Tyre numbers and staffing
Michelin will have a total of 1,100 dry- and wet-weather tyres for the South African race. Four dimensions are available for the Superbike runners: 18/67x17 (17") and 19/67x420 (16_") for the rear (slicks, rain tyres and intermediates), plus 12/60x17 (17") and 12/60x420 (16_") for the front. There will be a total of 800 dry-weather tyres, 200 rain tyres and 100 intermediate tyres. This year, there is no Supersport World Championship round at Kyalami. Michelin will have a total staff of eleven at the race (manager, two technicians, seven fitters and a press officer).
