Some general overview of some handy details for each type.
This was list was constructed using the original instruction manuals:
- Instruction manual 1939 for Tiger 100, 80 and 70, Speed Twin, 6S, 5H, 5S, 3H, 3S, 3SC, 2H and 2HC
- Instruction manual for 3SW model framenumbers TL-18101 to TL-30050
- Drivers handbook for 3SW and 5SW
- Motor cycle replacement parts 1937 models
We did notice some differences between the manuals, f.i. the fuel tank capacity for the 5SW. Both 3 and 3 1/8 gallon are mentioned. One of the biggest differences is the “exhaust closes ATC” difference between a 3S and 3SW. One speaks of 36° while the other of 29°.
