Tyre Warmers

Buy cheap buy twice IMO

Just ensure you get ones without pull cords they last five minutes

 

diamond are very good, well made and powerful enough to deal with the British cold

great after care too, my 8 year old set developed some holes from being too close to exhaust on occasion

sent them back to diamond, who repaired the holes with special heat proof cloth, re did both strings and toggles and even cleaned them of chain gunk
cost 20 quid inc return postage

new design is better than my old ones as they don't use the strings anymore

 

Question:
If you're racing, I can see the point of tyre warmers. But for a trackday? Won't they be up to temperature after a couple of laps? And if it's freezing cold, won't they just cool down after a couple of laps?
It always just looks like added expense and complication to me. But then maybe a lot of gizmos to do with trackdays look like that to me.

 

you are right to a point but if anything its more important on a trackday imho
its not so much about keeping them sticky enough to ride on straight out of the pits (you still should warm your tyres when you use warmers), its more about how many heat cycles the tyre goes through. keeping the tyres warm between sessions means that your tyres only do one heat cycle in a day rather 5 or 6 without warmers. doing this prolongs the life of the tyre

its less of an issues with road tyres (that are designed for more frequent heat cycles) but with slicks and road legal race/track tyres it makes alot of sense

 

Thanks for the explanation.
That all sounds very reasonable and logical.

 

With warmers you're keeping the tyres hot all day, rather than hot then cold, hot then cold, so you reduce the number of heat cycles the rubber goes through. Which makes track tyres last longer. Or something like that. I just use road rubber, but that's what I understood...

<too slow. As usual >

 

Ive used the same pair of Diamond warmers for about 7 seasons even when used on Supermoto with mung and spoo on the tyre they have held up .
Agree later design is better

 

Try Capit. They're a few quid more but you know where the dosh has gone. Mine get to 80 deg C and hold it there. A lot of warmers work off a thermostat so the temp is up and down like whores draws.

 

I have a set of Race-Tech warmers, you get what you pay for. I replaced the elasticated draw cords with sturdy nylon cord to make it a bit easier to fit them, also the rear warmer is barely just long enough to fit around a 190/55 profile tyre, I believe the later one are a bit longer.
All in all they are fine for trackdays when you have time to fit them properly, if I was racing I would spend more and get a better set.

 

+1 for Diamond warmers. I have a set and they seem extremely well made and warm up quickly. The elastic is strong and there's no strings to get caught around wheels or get frayed in velcro. Top notch kit for a good price.

 

yes agree capit are excelllent too

 

I've been running the MotoGp warmers for a year now and been very impressed fast warm up and regulate of the temp. with a light indicator. And agreed for track days warmers are really important as the tyres go through so many heat cycles

 

My last set of Warner's were from the German firm KLS. They have a two stage heat switch so you can put them on in the lowest temp(60*) and switch up to 80* 15 mins before you go out.
If you are planning on doing more track days then in my mind that are a must, as you will save 2 laps per session per day warming up your tires! And for me personally I found the more things I could do to reduce stress/ instil positives the better
