The 1968 Triumph Bonneville T120R Roadster
1968 Triumph Bonneville T120R Roadster sits at the top of Triumph's parallel-twin range as the sportier, US-market-focused sibling to the standard Bonneville, built for riders who wanted performance over touring comfort. This is a bike that rewards a rider willing to work the gearbox and stay attentive to the road, delivering the kind of tight, direct feedback that made British twins the benchmark before Japanese manufacturers caught up on refinement. Ownership means embracing some quirks: it vibrates, it demands regular maintenance, and it will leak a little oil somewhere, but it rewards patience with genuinely engaging power delivery and a top speed that still feels lively decades later. The 1968 model carried over without significant mechanical changes from the prior year, so buyers comparing it to a 1967 example should focus on mileage, service history, and condition rather than spec differences. Today's buyers tend to be experienced riders or collectors stepping away from modern machines in search of mechanical honesty, and with collector interest running high, well-documented, original examples of the 1968 Triumph Bonneville T120R Roadster command serious attention at auction rather than casual browsing.
