Hello, I'm new to this particular forum. I started riding over 50 years ago. A friend recently told me that he was going to make me an offer on his older TW200 that I can't refuse. So now, I'm starting my overly enthusiastic search for information. If purchased, this bike will be going up to the So. Cal. High Desert. I'm guessing it will get about 25% street use and 75% dirt. (Sand) Does anyone have a favorite tire combo for this type of use? (I'll also check out the forum but I wasn't sure if new tires were now available. Tires are one area that keeps changing all the time.) Thanks and I look forward to hopefully playing around with this iconic slow and steady bike.
