Brilliant bike BUT the road handling is compromised by the skinny 21" tyre (compared to other bikes, I am not saying you can't do big road mileage on this bike). The tubes don't bother me. I am not knocking the bike, I intend to keep mine for a long time and will do good mileage but there are a host of more suited bikes for big asphalt tours. The bike has a design goal which I think many people agree Honda has nailed. Take a day long test ride if you can.
250X7 (first bike 17 years old, T-Boned it in 3 weeks), CB250K4 (needed wheels), CB350K4 (last wheels needed replacing, ran engine without oil after rebuild, DOH!), T500 (didnt handle, didn't care, 2-stroke smoke - EPIC!), 883 Sportster (oh dear, mistake), 1340 Lowrider Covertible (stolen before a year old), Daytona 1200 (heavy, 147BHP mad lump), DR350 (reliable small thumper), CRF1000 (love it)
