Must be missing something, I agree with Terry. I can't find the 100/90V18 and 120/90V18 together in a classic radial either on the Conti site. But then I am a bit of a f*ckwit when it comes to finding my way round any website!  :D Stuart

I'm looking for a 120/80 front and a 150/80 or 70 rear in Road Attack 2
see they do a 160 rear but no 150
damn it

 
Thanks Hooksey, Didn't spot those two, I was looking for a matched pair.

You'd need to know exactly what that tyre on that rim measures- Avon Storms are wider than 150.

no problem, is not a standard swingarm or fork set

 
Well if Contis 160 came in at c.155 on a gsxr rim to clear the 'standard' offset sprocket and 520 chain (unlikely, I admit) that would be more tyre choice which can only be a good thing.
 
There is a issue if you end up with a 55 aspect rear tyre,when the dia gets that small I found I was turning 1000 rpms more than other Laverdas using more old school 80 aspect rears at the same road speed.Up the gearing to compensate and you loose acceleration in the same comparasion.Absolutely loved the grip with the Bridgestone BT92 140 x 55 radial rear but with the above it just didn't work for me.
 
Looks like a toss-up between the tried and tested BT45s or Pirelli Sports Demons. The only two brands in the right sizes that the place I get my tyres fitted stock.
 
I have a Sports Demon on the rear of my 3c at the moment,cannot complain.Its fine with predictable grip,done the usual full wet day on the Snowy Run and was fine in the wet as well.I am keen on trying these these Contis but they are getting spendy,be interested in how many ks they last compared to cheaper options like the Demons

Terry, I fitted a 530 X ring with new sprockets some time ago, and am happy with it.

Aha, back to the thread subject, thanks.

I am going to do the same, getting a kit to replace my 630 setup from Laverda Keith in sunny Scotland.  :D

Terry I pulled a sport demon off the front of "Vinces" RGS and fitted a Pilot Activ, no not a radial, but on Levo's recommendations, as he told me that the Conti Radials were hard to come across and expensive. Well let me tell ya so far the Pilot is great and no front end shimmy on the RGS. It looks a lot like a radial and has a very nice profile.
I think will end up with them on all the bikes as the sport demon's seem to scallop up fairly badly then cause vibrations/shimmy in the front end.
530 chain set up on the RGS 19/40 think it was 106 links puts the wheel right up the front of the slot, have done about 10K thus far and only adjusted the once.

Yep, did the same for me. except I haven't needed to adjust it yet.
 
Mine arrived this morning from Keith at Laverda Scozia ?119.50 all in which I reckon is pretty good for a Z1R super heavy duty Gold X ring chain and sprockets.

Slaters wanted over ?40 more............

I've got stitches in my left elbow following an operation to remove some spur or whatever, so won't be fitting it this weekend. I'll let you know what I think of the "vastly improved gear change" as soon as I can.
