Unit construction Tiger started off as a tuned 5TA but in ’61 gained its own identity as the T100SS. Post ’67 have much improved chassis, the ’69 model has good TLS drum front brake. The 1970 36hp T100C suffered from poor build quality but had nice chassis and interesting blend of performance and economy. The single carb 500’s arguably Triumph’s best engine as it didn’t suffer the trauma of excess vibes whilst retaining useful urge.
