Triumph Bonneville Speedmaster keeps an estimated 66% of its value after 5 years — #567 of 1005 powersports vehicles VINdown tracks. See its full depreciation curve, cost per day, and best model year to buy.
Per VINdown's modeling, the Triumph Bonneville Speedmaster retains an estimated 66% of its value after five years, ranking #567 of 1005 powersports vehicles we track. That trails the 74% five-year average for Cruiser in its class by 9 points, so it depreciates faster than most rivals.
Most of the loss lands early: the Triumph Bonneville Speedmaster sheds about 10% of its value in year one alone. From roughly $13,995 it falls to around $9,166 by year five — a five-year loss near $4,829, about $2.65 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used Triumph Bonneville Speedmaster bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
