From a press release:

PROGRESS CONTINUES FOR EDWARDS IN SOUTH AFRICA

Castrol Honda¹s Colin Edwards was 0.7 of a second inside the lap record on the second day of the Michelin tyre tests at Kyalami in South Africa on
Thursday.

Modifications to the Showa 2002 specification front forks improved the Castrol SP-2 as Edwards came within 0.03s of his fastest-ever lap at
Kyalami, recording a time of 1:42.22.

“We made the changes to the forks this morning and the machine was instantly better,” reported Edwards. “The test is supposed to be about tyres but Michelin know that we can’t test anything until the base setting for that particular circuit is right – by lunchtime today we had it.”

Edwards added: “My best lap came on a rear race tyre which is always a good sign and we had a 45-degree track temperature today, a lot hotter than the race here last year so that makes today’s lap time a little bit more satisfying.

“The HRC engineers played around a little with the fuel injection and I got dialled into some serious tyre testing with the Michelin guys this afternoon so all in all we¹ve had a good day.”

Two days of the test remain and Edwards hopes to test a new Michelin Superpole rear tyre on Friday.
