Metzeler's best-selling trailie tyre, the Tourance, has just been upgraded and renamed the Tourance EXP.
Using lessons learned from road racing, it now features a new compound and construction, and is the only tyre in the class to have a zero-degree belt construction in the front tyre. The EXPs are designed to cope with faster riding as well as being more stable, longer lasting, quicker to warm up, make you more popular with women etc. etc.
"To find out if those claims had any foundation we had a good old 350-mile thrash from Marseille to Turin along some of the best biking roads on the planet. At the end of the dangerous riding competition the verdict was simple: the EXPs do exactly what's on the wrapper and let you ride like a complete twat without sending you to A&E.
"I tried them on a V-Strom 650, a bike I've got lots of experience of as it's my long-termer, and was well-pleased with how they performed. They're a lot grippier than the standard OE Bridgestone Trail Wings my own bike's fitted with, a fact I discovered when I nearly crashed after trying to ride as hard on them as I had done on the EXPs down in the South of France.
They worked well on the BMW R1200GS I also had a go on too - a bike that's likely to come fitted with EXPs as standard in the very near future.
"They're designed for road use, though they can deal with a bit off light off-roading and will compete with Bridgestone Battle Wings and Michelin Anakees. If you want some, you'll have to hang on until June when they'll be in your local tyre shop. Be prepared to spend about a tenner or so more for a pair than you would for the current Tourances. Extra money well spent I'd say."
