I ran a 70 all last season, then we started this season on a 60 - coz thats what was fitted from the showroom. Did Cadwell, Brands and Assen trackday on it and didn't really notice any difference (forgot it was a 60 actually).

However, I prefer a 70 - even it's psychological.

A racers head is as important, if not more important than anything else on the bike etc.

i have run both 60/70 profile in the last 2 years...and imho it makes no difference at all...................

as ali points out...there are arguments for both..!.......as for riding of the edge of the tyre.........................LMAO

[Rattler]

In theory its contact patch - in reality its mental!!!

Can we go race yet ????

Well all ye non-believers ... when I ran the 60 profile, the tyre was worn all the way to the edge and the I slid the front more easily than on the 70.

When I used the 70 I've never gotten to the edge, there's always been a few mm left, and the tyre has only slid when the tyre was worn.

That was my experience FWIW

Bearing in mind that sliding the front is not necessarily just a result of speed, it can also be a result of how you're riding the bike.

Just my opinion

Talk about a 'how long is a piece of string' type question!

Bike geometry, body position all effect how much load is on the front. At as much lean as we carry on these things the 70 has a bigger contact patch and the 60 has less, so if you're already on the edge where the 60 offers you less grip it stands to reason that you can slide it easier.

Phill you're lighter than me, a smoother rider and therefore you could be running your bike with less ride height, different fork internals etc ... lots of reasons why I get slides and you don't.

The list is endless

Less ride height??? You can walk under Fil's yellow 583...

Now mine & Chris Woods, you need a feeler gauge..

Hey dom..
When i took the bike to cadwell for the first time(last year) it was running the 60 profile front and found it to be terrible under brake's/turn in.....wallowed like a pony!!!!

I Think it all depends on how you brake/turn/ lean????
If you brake full on into a turn i think a 70 profile is a must....
If you do all your braking before turn in then a 60 should be ok providing youv'e not loaded the front up to much??
