It's not so great when you're cartwheeling down Duffus Dip and back into the path of another vehicle...
True. And thats why driving cars seems a bit tame. Follow link and play the next 3 pics. Both were OK(ish) I should add. wink

BSB Superstock, and Superstock Cup was definately not in the dry in 2007. That I can guarantee. laugh

Superstock lap record is a 50.8 sec lap. Superbikes were 48's in practice. clap
They're not road standard though are they? Superstock bikes run slick tyres and a wet weight 15kg less than the factory list dry weight. You can't compare a race bike with a road car!

Superstock bikes use road tyres, not slicks, standard engines, and yes the road gear is taken off, but then they are always going to be lighter than a car. So 15kg isnt exactly the real issue is it? Bit chalk and cheese. Cars are faster around a track ultimately, just not these ones.

I have to admit it's a strange comparison yes, but for a wet weight, 15kg off the dry weight is quite a lightening for a motorbike! It's equivalent to a lightening of over 10%. The equivalent 10% weight off a Caterham would be 45kg, which is a fair chunk! (For comparison, I weigh 67kg...).

My apologies - I thought they ran on Metzeler racing slicks. The tyres are full racing ones though aren't they? Equivalent to something like a Yoko 48R on a car? Something like this? :

You're right, around most circuits that I've seen a comparison done on, Caterhams edge out bikes by a second or so. Bikes generally have the edge on circuits with hairpins followed by straights, or very tight sections created especially for bikes - like Silverstone circuit for bikes for instance - I think a road spec bike can pip a Radical SR3 by a few tenths around there (EVO compared a Crescent Suzuki with an SR3 a year or two ago).

Personally, I'll have both please smile A Fireblade or an R1 and an R400 or an R500 in my garage would make me a very happy man. Neither in illuminous colours though please wink

See my link and analogy above. The Yoko 48R for cars is a similar tyre - road legal but very soft and blindingly quick. I still think my link to those stock bikes run by amateurs is more akin the Caterham times I found for road legal cars run by amateurs, rather than the Metzeler SS BSB support race series.

I agree both are great fun yes

Your link is to the MST results for Metzeler Racetec National Superstock series which supported British Superbikes in 2007. If you look in the bottom left hand corner of the results you will see one of the qualifying sessions, warm up, and the race were run in the wet, so the 60 sec times by amateurs are actually wet times by the series I mentioned. The race was abandoned by the way. Check the other qualifying session and you will see everyone was doing between 52' and 50.7.

The real amateur racers can do 53's. As can be seen on www.mylaps.com

Ah, my apologies. 53s would be about what an R400 would do round there, which to be honest goes along with the times I've seen for R500 vs bike shootouts in the past. My original post was just trying to state that a bike is not necessarily the fastest way round a circuit, but you seem to be very aware of that anyway smile

For sure. You cant beat having 4 bits of rubber on the ground. Simple as that!

And you cant beat having half the grip for making it more fun. smile imho.

But less of that. How was Gareths driving in the vid?

yes agreed! yes

I'm a big fan of in-car video, but sadly You Tube is blocked at my work. I'll check it out when I'm home on Friday though yes

I don't know KH but seemed pretty smooth and the car is certainly quick - perhaps a little more kerb abuse wouldn't have gone amiss although there's a YouTube vid of a trackday where a Westie hits one of those tyre stacks or whatever they are - ouch.



I note the "forum owners" have backed down wink
