A/ I was forced to use that chassis - at least I made it around 3 times stiffer than stock...But still not directionally stable at that power level - with me on board anyway. Frightening actually.
B/ That rider was/is under the impression that gutters and kerbs are part of a race circuit and are there to be used...If he was in the gutter at the hairpin, it was intentional...

i'm over buckets
probably still is hoggie
but if revingtons hotel demolition goes ahead it might give the chance to run greymouth in reverse direction, As its removal would give a run of for the back straight.
Assuming they removed the kerbs. It might be great fun to wear out the left side of a few tyres.
It would be a dam sight faster as well. likely be even safer too.
I don't want to be different. But the missus keeps telling me that I am .
Neither were Aprilia, Derbi, Honda and KTM (in alphabetical order).
But they all established that 1270 mm was too long for 125cc GP-racers on GP-tracks, and ended up with about 1215 mm (47,8" in Grumph currency).
There you go Grumph.
Racebikes are not meant to be directionally stable. H-D are catering for stable.
The majority of 500cc GP-bikes were shaking like mad on the straight-aways, but when I asked their riders about it, they didn't even know what I was on about;
none of them registered unstable bike behaviour as anything peculiar. They were more concerned about their bike being too lazy turning in.
That rider was right. I remember drifting against a kerb in a corner. The first time was unintentional, but then I realized I could give it full throttle while against that kerb.That rider was/is under the impression that gutters and kerbs are part of a race circuit and are there to be used...If he was in the gutter at the hairpin, it was intentional...
You gotta use what you come across.
I'd love to get you on that MB100, Frits, making a rubber band three times stiffer doesn't change it from a rubber band, LOL.
Yes, I do appreciate what benefits a short wheelbase offers. I do build as short as possible given the engines and suspension constraints I'm frequently forced to work under. I also understand the geometrical quandries that riders find themselves in when trying to get a bike to turn. Jack up the back - drop the front - then hang on for grim death.
As an interested observer, I've watched tyre development and talked to riders here. It would appear that some brands have adopted a carcase construction which is more directionally stable than others. Some turn very readily - which seems to mean that those brands suit a stable chassis better.
On coming back and re-reading Frits post above, I'd add that i'm not building for GP circuits either. Anything I build is very likely to be used on the street circuits here in NZ - which are littered with bumps. surface changes and manhole covers. Both from observation and talking to riders, a GP focused chassis such as Honda RS125's or TZ's are not a comfortable ride on those tracks.
This is one of my engine customers. While I'd love to talk to Rossi, I think I got the gist of what it feels like from this.
