Interestingly it was Warren Willing, on a trip stateside who introduced the Aussie 'superbike' racing concept to Americans, AFAIR..

I am of the opinion that it was this type of class that has lead to the debacle we have today.

 

There is a place for modified production bikes but not as a premier class.

Yeah, well, two points on that,

 

1, Sheet home the blame current malaise-wise squarely on Carmen Dorna..

 

&,

 

2, Back in the day the new production bikes ( 1969 H1 500 Kawasaki 60hp = 1963 500 Manx Norton 60hp) ,

were just such a high impact item..

H1 handled like a frame of overcooked spaghetti and it ain't all Mr Expletives fault completely he has been ably assisted by the evil empire that is Honda.

Correct about Honda, their 'influence' based on a bizarre ideological anti-2T agenda has been most baleful..

 

& as for 'spagetti' handling, well, the featherbed providing a dream ride wasn't enough, by the end of the decade.

 

Kiwi GInger Molloy beat out all the pukka 500 G.P. racers - with fewer than 3 cylinders - in the `70 World Champs,

on an H1R..

Yes indeed the HIR was a very good tool and although it was based on the HI (like the TZs were based on the RD series) Kawasaki did produce it as an out and out GP racer. 

Its' only real challengers in the 500 cc 'production racer' (by that I mean a dedicated racer produced for public sale) was the Linto, which despite early promise had many flaws which resulted in its' demise. The other, of course, was a 351 TZ (or TR in 1970). The 500 Suzuki twins of the time were converted road machines as the factory only ever produced the RG500 for public consumption later in that decade.

There is avery tasty H1R for sale on Hubert Rigals' site at present:http://classic-racin...-500-1971-fc71/

My H1R replica roadbike I built a couple of years ago, a good fun ride, did 600 miles on it last year and a couple of classic trackdays
