    I'm a veteran road motorcyclist but recently discovered the amazing new dimension of off-road biking. What a pleasure! I bought a second bike after I had been hugely disappointed by all the niggles I experienced with my 2000 BMW F 650 GS and sold after only 10000 km's ( starter motor relay switch defect, surging, radiator leak etc.). I now have a 2001 Transalp XL 650 V which is all I want in a motorcycle for my purposes.
    Something puzzles me, however. Why do all trail bikes persist with spoked rims and tubed tires? I am only aware of the BMW 1150 GS that has spokes and tubeless tires. My guess it has something to do with weight, flexibility, but the penalty and risk of tubes blowing out still seems not worth these properties. Or are modern day tubes (and tires) less likely to suffer blowouts? And if this is a risk that we have to live with, is there anything one could do to minimize it, like liquid sealers and the like?
    Look forward to your wise counsel.
