16 years of progress

[Joni]

I did not know that about you Jimbolenah... you never cease to amaze me

[sugilite:Me]

Shame, that was a VERY respectable time, esp for your first race....RESPECT

Garry, The cambers have never changed. They resealed Manfield just before that round of the supers and it was like a billiard table!
Ahhh, those were the days, I could do 1:15's on a standard GSXR750, hold it, I can do 1:16's on a standard 1989 ZXR750 now days! Guess I'm getting crazier with age

How times change ? Crosby had the lap record at about 1.23.5 in 1974.
( Z1 900 Kawa) !!!!!!
Wonder what a modern production bike would do 33 years on ? Gaz.

Actually what would be interesting is what 33 years progress in tyres made in lap times? Take say that Z900 and fit the stickiest tyres possible, guess you'd need to fit 17" rims. Then maybe fit 33 year old tyres to a K6.....

Sean Donnelly is doing high 1:16's in post classic on a moderately modified Z900

You'd want to video that. A Z900 would tie itself in knots with tyres that sticky. I haven't ridden it for a while but I did ride the McIntosh in about 1983 with slicks, mainly Dunlops, and later in about 1992-1993 on Metzler Zs and the REAL big differance was just how progressive the Metzelers were. They seemed to have comparable levels of grip. Of course we're talking about another 10 years of development after that.

Although still a heavy thing , Sean's Z1 is quite trick ! The motor probably has 50 bhp more at the rear tyre, with modern rubber, wheels and Susp.
New , a Z1 probably had under 70 bhp at the tyre ? ( a TT100 !!!) Gaz.

The Cheeky bugga told me it was lightly warmed over

[bistard]

You arnt actually going to belive a bike racer as to what he has done to his bike are you??
Plus how many engines & state of tune has Sean had over the years,I remember beating him to the line in the masters race at Wanganui a few years ago on my ZXR400

[bistard]

Actually I did the same to Murray Cross on his McIntosh the year before
Go the little ZXR!!!!

So to look at this another way Crosby was around 20 seconds slower per lap than an open wheeler. And now the fastest Production Superbikes are around 2 Seconds slower than a comparable open wheeler (Formula Toyota)

Motorcycle tyres really were shit in the seventys.
