General information about the Triumph Bonneville T100

The classic standard shape starts on a time-tested, double down-tube / double-cradle frame made from tubular-steel members; a construction method that continues back into the yoke-style swingarm. A steering-stem angle of 25.5 degrees gives us 4.1 inches of trail and a 57.1-inch wheelbase between the 18-inch front wheel and the 17-inch rear with a wide steering sweep that makes U-turns a breeze.

KYB products support both ends of the ride with a pair of 41 mm forks up front and a brace of coil-over shocks in back. The rear shocks get the only adjustments with the obligatory variable spring preload, but both ends enjoy a full 4.72 inches of wheel travel. While that isn’t enough for anything rougher than light terrain or poorly-maintained roads, it’s certainly enough to make your daily commute a fairly pleasant experience.
