I Ride: 2015 Panigale R , RD400c , RGV250 ,KTM300,i also own a Harley and a boat , the Harley is the anchor.
i use to use all my old rear racing slicks on my road bike ( RC30), i would just put a few cuts in them with the tread grooving iron just to keep Mr Plod happy,they were Michelin tyres back in the day,they worked fine,just not good in the wet.

Slicks will really reward you if you can manage them , otherwise they'll burn hole in your pocket. You made a good choice with sc1F and sc2R to start with. Cold days and cold track will suck the temp out of those really quick , so you have to stay on the pace !!!

Most important thing i have learnt is to understand what temps your tires are operating at for that particular day and how the temp chamges through the day. Big mistake is to set your warmers at 80 degrees and set your pressures at 34F and 27R then go out and your tires can only generate 50 degrees which will have pressures drop and you will get cold tear and destroy a tire in a few sessions.

If you can guess your temp on a cool day will give you an operating temp of 60 degrees , set your warmers at 60 and set your pressures to match 60 , then crank them up to 85 (this allows some cooling off getting on track and up to speed in the first couple of laps). Do your first session and get into pits on pace and check the temperatures .

First signs of cold tear put a couple of psi into the tire. Common mistake is to deflate the tire to generate more heat. This only spreads the contact patch and cools the surface rubber which then starts to break apart (cold tear). It does this because the tire is not hot enough for the compound to stay bonded together.

If on the other end of the scale the track surface is stinking hot , your setting track records, your getting excessive temperatures in your tires, you would be needing to go for a different compound i.e.; sc1 then sc0 in that order for the rear and move to an sc2 front (sounds the wrong way around ).

Read as much Dave Moss as you can find .


You have me nervous now. But I'm going to pay acute attention to the tires. Was going to start off with 31F and 25R psi cold. But I only have a single temp tire warmer so I can't set it to the exact temps. Will probably be colder in the morning and then warming. Am I correct in thinking I should maybe start with lower PSI and increase as the ambient temp rises? Pirelli recommends 30/32 F and 23/26 R cold.

you are correct on tire pressure. I run no more than 30 and 26 hot. Thats my sweet spot (with T Hill) where I can lean to 55-56 for elbow dragging. lol.

I run my front at 36 psi hot and 26 in the rear . Run a few PSI lower in the rear on a SC 0
