Triumph T140V and TR7RV- Best Used Motorcycle

These so-called oil-in-frame Triumphs were the ultimate evolution of Edward Turner’s 1938 Speed Twin but are less valued by collectors.

YEARS SOLD: 1973–1983
MSRP NEW: $2,895 to $3,995
Current Market VALUE: $3,000 to $7,500
BASIC SPECS: Some 60,000 twin-carburetor Bonnevilles and single-carb Tiger 750s (and other variants) were produced. The classic air-cooled, parallel-twin displaced 724cc on early bikes but after mid-’73 was bumped to 744cc.

Early five-speed gearboxes shifted on the right; 1975 and later were left-hand shift. Front disc/rear drum brakes (’73–’75) became disc front and rear (’76–’83). Twin front discs were used on some ’82–’83 models. Dry weight ranged from 412 to 440 pounds.

WHY IT’S DESIRABLE: These so-called oil-in-frame Triumphs were the ultimate evolution of Edward Turner’s 1938 Speed Twin but are less valued by collectors than pre-’71 models and therefore more affordable. A mid-14-second quarter-mile time and 110-mph top speed remain adequate for use in modern traffic. Brakes are decent even by today’s standards, and handling is quite good. A well-set-up bike’s clutch pull and throttle effort will be on the light side.

Reliability when new was spotty due to poor assembly, but a well-sorted machine can be very reliable—and oil tight. Parts and service support are exceptional. These bikes were essentially vintage when new but are fast, fun, and practical to this day.
