Triumph T120 T140 T150 T160 Trident OIF Unbranded Progressive Rate Fork Springs PN# 97-4011 P KIT

If there is one significant improvement you can make to a post 1970 Triumph or BSA front end, it would be a set of these unbranded progressive rate fork springs. These will work like the branded but saves you money. They will fit the following:
• 1971-72 T120 Bonneville, TR6 Tiger, TR6C Trophy
• 1971-72 BSA twins
• 1973-82 T140 Bonneville and TR7 Tiger
• 1971-75 T150 and T160 Trident (due to their weight Trident models may need the use of a spring pre-load spacer supplied in the kit).
