What are the best tyres to fit to my Le Mans 2, I am planning to do the classic spa and IOM classic so looking for grip rather than mileage.

Thanks

Do you run a 110 front and rear. 

A lot of people think running a larger tyre upsets the handling.

Yes & yes, strictly 100 front 110 rear. In fact wider front won't fit in the mudguard, even if it's actual size is bigger than a 90. Guess how I know. I'm assuming you have the stock plastic mudguard.

There's also a possible issue of a wide rear rubbing on the swingarm.

What I was told was the Tonti frame was designed with narrow tyres in mind. That is, what was normal for the period. So yes wider tyres can screw things up handling wise.

My choice would be AM 22 110/80 rear and AM 26 90/90 front, my favourite combo on a 500, but I never raced a heavy bike like the Guzzi. Also don't like fat front tyres as a rule.

If you go the Avon route, make sure you get the right compound for front or rear, not all dealers are knowledgable, or care about the difference. Front compound on a rear wheel gets ripped in no time.

Motorsport or road tyres? Avon cunningly use the same names and numbers ...
Road -
I had "issues" with the diabolical sport Pirelli on my V7ii and completely resolved with  Avon RoadRider (AM26, road version) fore and aft in every department, grip, braking, cornering grip, steering, tram-lining, wet, wear, speed rating. The ABS doesn't kick in so early because the tyres actually grip the road.  Roadriders come in front, rear and universal. Apparently the compound is the same, so it must just be the bracing. Also considered and upgrade to BT45 on Bonnies. Cat on rails.
Motorsport -
AM22 and AM26 Avon-Motorsport are both soft compound race tyres but are road legal. Wider tyres increase the lean angle needed, and the unsprung weight.

AVON AM 22 & 26 racing compound tyres are clearly marked: "FOR RACING PURPOSES ONLY - NOT FOR HIGHWAY USE", or "FOR COMPETITION USE ONLY".

I use:
Battlax BT45 
Front tyre: 100/ 90 18 56V Rear tyre: 120/ 90 18 65V). 
The back fits a 120.

Haven’t had any problems with them, need to renew in the spring as they are down to the minimum so will probably go with the same unless this thread leads me to look at something else...lol

Best advice is to always check the tyre pressure every time you ride...this is the biggest differential for handling....but we all know that...36 front for me and 40 back.

Right can this be swapped to the Toni frame section?
