Triumph's Sprint ST sport-touring motorcycle is quite capable of wearing its tires down to the core, thanks to its voracious appetite for long rides. Changing the front tire is a straightforward process, but the Sprint's unconventional single-sided rear swing arm presents a unique challenge when removing the rear wheel. While the rear wheel isn't too difficult to remove, a specialised swingarm stand is required to hoist the rear wheel off of the ground. Investing in a rear stand may not be worthwhile, unless you plan on doing all of the motorcycle's tire changes and maintenance yourself.
