A dragrace?? :imaposer:

In the USA, where dragracing is huge, nothing touches Harley-Davidson.

What does this say?

Only in the Superstock class and that is because bikes using engines derived from the Harley design can have a displacement of up to 2620cc,  four valve heads and engines can be built from the ground up without having to share parts with production items.

Other manufacturers are limited to 1750cc , 2-valve heads and the crankcases  from production bikes. 





American rule makers have always been like that, ever since the 1940's. To them, 'fair competition' means that Harleys must be allowed a capacity advantage over the foreigners.
After all, everything's bigger in America.  :imaposer:
Sounds like the Ducati 916's in superbikes while the Japanese had to do with 750cc  >:D

As Sidetrack pointed out, like the WSB series, where Ducati has been favoured for many years.

Ducati only bikes running with restricted airflow intakes in WSBK.  How does this work in their favour?

Because they cannot handle the full flow?

Was referring to the Foggy era (never been a fan of that guy), I think now all the bikes are around 1000cc ? How I smiled when John Kocinsky (sp) won the title in 1997  8) Then offcourse Fogarty had a go on the Honda the next year and finished nowhere !

Around 1000cc?

SBK rules in terms of engine capacity is:

4 cylinder = 1000cc
3 cylinder = 1100cc
2 cylinder = 1200cc
