I bought my T-100 new and now have over 30K miles without any serious problems, even after a low-speed crash and dealer repair. Did notice that without using a Battery Tender the original battery lasted only about 8 months (just changed out my second one recently). A minor glitch which seemingly has self corrected is that the tach needle would get somewhat squirrely at about 4K, the needle wavering +/- 500 rpm, but since replacing the battery that seems to have settled out. I donĀ“t do much wrenching, other than oil changes, brake pads & chain adjustments. Would appreciate any comments/feedback from others.
