This KTM is turning out to be an interesting antidote, a mobile rehab platform for the incorrigible tinkerer. What few mods I've made reflect a desire to improve the bike's throttle response, add some utility, and test new rubber. On that front, the Bridgestone T30 sport-touring tires are still going strong. I measured tread depth down the center of the rear tire just above the TWI (Tread Wear Indicator) bars. The depth ranged from 3.0 to 3.2mm. Considering the tread is approximately 5.9mm deep at the TWI when new, I'd expect the rear T30, which has 4,427 miles on it now, to last 8–9,000 miles easily. The front looks almost new.
