From a press release issued by Proton Team KR:

LAST RACE MARKS END OF THE BEGINNING FOR PROTON KR

Sunday’s GP of Valencia closes a hectic 2003 season for Proton Team KR. While rivals have contested some of the most competitive blue-riband racing ever, the unique England-based racing manufacturers have been engaged in an even greater struggle.

The task is as before: to design, build, develop and then race a fully independent specialised Grand Prix motorcycle, against the full might of the Japanese and Italian factories.

The challenge of 2003 came with the new 990cc MotoGP four-strokes, now in their second year. Former triple 500cc champion and racing legend Kenny Roberts swallowed hard at the much greater costs and technical complexities, then decided to make his own high-tech V5 four-stroke.

The season began as engineers were still destruction-testing the first batches of engine parts. After testing only on airfields, the bike saw its first proper race-track at Le Mans, where it ran in practice for the fourth round of the year. The testing and development programme began directly – not in private, but in the full heat of the GP season.

The new bike started fitfully, but almost day and night work by the team and back at Banbury saw it become steadily faster and more reliable over the coming races. At the 13th round, the howling Proton KR V5 scored its first points, when Nobuatsu Aoki was 14th in the Pacific GP. It was only the seventh time the bike had raced, and the result came in the Japanese heartland of the dominant racing factories.

Two races later team-mate Jeremy McWilliams was a strong 11th in Australia, underlining a late-season turning point for the infant racer.

Aoki and McWilliams will race basically the same machines at the final 2003 round at Valencia, but the end of the beginning is also the beginning of stage two. Both riders will stay on after the final Spanish round for two days of testing a brand-new chassis … the first of a series of evolutionary developments that will take the V5 motorcycle on from first prototype towards fully competitive racer.

“We’re looking forward to this race so we can get on to the next step,” said team manager Chuck Aksland. “We’ll be testing a new frame that is more towards the 2004 machine, back to back with the old one.

“We take that information back, then build it in to the bike we will test at the beginning of next year with some redesigned engine components – the cylinder head will be the first, with more modifications coming probably after the first few races,” continued Aksland.

“The whole motorcycle will be tidier for the 2004 version … but it’s more evolution than a complete overhaul,” he revealed.

“We’ve raced the four-stroke for six months. We’re confident we can make the chassis performance better. We know we need more engine performance, and we’re working on that right now.”

The Valencia GP is the 16th round, and the third race in Spain. It closes off a season already won by defender Valentino Rossi (Honda).

NOBUATSU AOKI – SOMETHING SPECIAL
I’m feeling better after some problems in Australia after I hurt my neck. Now we come to the end of a very interesting time – even in the flyaway GPs, we got small step by step improvements. I can really see the progress, and I know the factory has made a very very big effort. I expect more improvements for Valencia, so I am optimistic. And also looking forward to testing on Tuesday and Wednesday with the new chassis. I have been with this bike from the very first, so it is something special to me, and I hope I can continue with the development.

JEREMY McWILLIAMS – GRABBING MY ATTENTION
I hope this won’t be my last race with this team. I would dearly love to continue with this project. Some of the flyaway races showed a lot of promise for the future of the bike, and it’s grabbed my attention again. Valencia is a very stop-start circuit, and that’s quite difficult for us. There’s no problem getting the bike stopped and into the turns, but we get hurt on exit speed. We need a little more grunt! But Motegi is also stop-start, and I’m certain I’d have been in the points there, but for a braking problem. After the boost in Australia, I know I need to finish in the points again.
