Urgent: New tyres

[muthaf9cka]

As regular readers may know, I have a fairly new Kawasaki KLE 500. Unfortunately, the combination of hot London weather, mostly road riding and 1500 miles in 2 months have knackered the front and rear Dunlop Trailmax tyres. I'll gloss over trying to ride it like a race bike and 90 mph up and down the M3 (I was running it in, be fair...).

I now have a golden opportunity to try other types (always seek the positive) but I have no idea what to buy as they keep offering me too many choices. There are several considerations to make. Firstly, I have a 400 mile round trip to Devon to make next month and normal usage for someone who only rides bikes in London. Secondly, I am riding to the Italian F1 GP the following month so add at least another 1400 miles. Thirdly, I mainly ride on the roads, but I like riding off road where I can even if it is rare. Fourthly, it's been very hot and September is usually hot in Italy. Finally, I don't have much money and my realistic upper limit is £120 for a pair.

My tyre types are (Front) 90/90-21 54S and (Rear) 130/80-17 65S. I believe that's pretty much the same as a BMW R100GS/R80GS, a KLR650 or a Yamaha XT660R. I was thinking along the lines of Avon Distanzias or Continental TKC80s, but I understand Metzeler Tourances are popular, but I've no idea whether they'd fit or not. Basically, they need to be cheap, long lasting and usable off-road. Any advice or anecdotes would be highly appreciated. And the sooner the better as I'm hovering on the edge of legality as it is.
