Horsepower Bhp:
Approx. 50-55 bhp (at 6,500 rpm), subject to specific tuning and model year.
Torque Lb-Ft:
Approx. 45-50 lb-ft (at 4,000 rpm), subject to specific tuning and model year.
Carburetor Type:
Typically Amal concentric carburetors (e.g., Amal 930/932 variants), single or twin configurations depending on model.
Fuel Type:
Leaded gasoline (historical specification); unleaded compatibility and required octane rating will be detailed.
Type:
4-speed or 5-speed sequential manual gearbox (specific to model year within the range).
Gear Ratios:
Detailed in the manual for specific gearbox variants.
Clutch Type:
Wet multi-plate clutch, cable-operated.
Drive Type:

Safety Standards:
N/A (Motorcycle of this era did not have standardized crash safety ratings as modern vehicles).
Braking System:
Drum brakes on earlier models, with disc brake systems introduced on later T140 variants. Manual covers both.
Lighting:
Headlight, taillight, brake light, turn signals (where fitted).
Instrumentation:
Analog speedometer and tachometer, ammeter, oil pressure light, neutral indicator, high beam indicator. Manual will detail their function and troubleshooting.
Ride Aids:
N/A (No electronic rider aids present on models of this era).
Connectivity Features:
N/A (No modern connectivity features like Bluetooth or GPS).
Oil Change Interval Km:
Typically every 2,000-3,000 miles (3,000-5,000 km) or as specified by model year in the manual.
Valve Clearance Check Interval Km:
Typically every 2,000-4,000 miles (3,000-6,000 km).
Engine Oil Type:
Classic motorcycle-specific mineral oil (e.g., SAE 20W50 or SAE 30), often with a high zinc content. Specific recommendations will be in the manual.
Transmission Oil Type:
Gearbox oil, typically SAE 30 or SAE 80EP. Manual will specify.

Heritage Summary:
Triumph Motorcycles Ltd. is an iconic British motorcycle manufacturer with a rich history dating back to 1902. Known for its parallel-twin engines and classic sporting motorcycles.
Evolution Overview:
The Tiger model line has a long lineage, evolving from earlier Triumph twins. The 750cc Tiger models, primarily the T140 series, represented an update and increase in displacement from the popular Bonneville and Tiger 650cc models, incorporating disc brakes and 5-speed gearboxes in later iterations.
Manufacturing Period:
The core 750cc Tiger models (T140 series) were produced from the mid-1970s into the 1980s, with the manual covering a broader period to encompass related models and variations that share significant mechanical components.
Manufacturing Location:
Meriden, Coventry, United Kingdom.
