What 2004 Triumph Bonneville T100 owners say
Most recent owner complaints, unedited.
As I was pulling out of a gas station onto the road I heard a pop and felt a vibration in the handlebar. I pulled over and examined the front wheel because that's where the noise seemed to come from, everything looked fine with the front wheel so I drove off at 35 MPH, the speed limit on that road, and about a mile down the road the bike felt wobbly so I pulled over again and now had a flat rear tire and noticed one of the spokes had broken off the left (brake disk) side of the rear wheel.
