Holy Resurrected Thread Batman!
Hey folks,
When I bought my Thruxton the tires were a bit bald and just getting worse. They were the original set, Lasertec front and MEZ2 rear. They got so bad that they followed every groove in the highway which was very unsettling and every time I rode over a botz dot the whole bike would get all out of whack and pick up a small wobble for a bit. It got so bad that when I would approach a curve I would slow way down because the bike seemed to get all funky when i tried to lean it. Now, I've ridden lots of different bikes with bald tires, but nothing was ever this bad. I knew I had to deal with it ASAP, but schedules and funds were preventing it from happening right away.
So, I spoke to my tire guy the other day. He's a total pro and knows just about everything about tires and wheels. So we were discussing my needs and I told him about my tires and the bike. He looked it up, checked out the geometry and asked me the standard questions, yadda yadda. He was wondering why there was a radial on the back since it's not a good idea to run a radial with an inner tube. I guess radials will get pretty hot with a tube in them. He recommended the Pirelli Sport Demon's and said no one really makes a tire in those sizes for that kind of bike anymore, but Pirelli does and they would be perfect and then he went into explaining how he had them on his XR750 racer and they were the perfect cafe racer tire etc. So we ordered a set, 100/90-18 front and 140/70-17 rear. They make the tire in an 80 series profile too but we figured the 70 would be a little more stable.
When they came in, I dropped off the wheels. I also told him about some of our forum discussions regarding spoke breakage and asked him to check the wheels out and tighten them up if they needed it. I got the wheels back today and they look fabulous. He said the front was good but the rear was very loose which was probably the reason the bike handled so poorly. He commented that spoke breakage is mostly caused by loose spokes so have them checked regularly, (I already knew this and I check them on all my services). He did have to add a lot of weights which isn't a problem, but I'm sure Triumph is using very cheap rims. Both wheels got completely done; new tubes, rim strips, tires, mount and balance, spoke tightening and disposal for $330.
