Correct. But Simmo was on a 4 valve Weslake as well and PC sailed past him. I was there in Katowice in September 1976 and no one was going to stop PC winning, he came from the back and he won from the gate. Only point he dropped was when it didn’t matter (his last race) and why take on Mauger when all PC needed was 2 points. Job done - fantastic day, and the only world final I seen live abroad. We went for one reason, to see PC win. He didn’t let us down.
And as I remember just a few weeks back Zmarzlik had THE rocket ship of the meeting at the last round in Toruń but still couldn’t win the meeting, in fact he didn’t qualify for the final. This shows you may have the fastest bike but you still need to be able to do the winning.
No doubt TW is a great rider, but it’s too difficult to judge the “best Brit ever” when comparing across different eras. PC was the best Brit of his era, and TW is the best Brit of his era by a long long way - he don’t have much to challenge him, but he is also class on the world scene.
