10.4.3 Classic Sixties – updated verbiage:
Triumph T100 unit-construction. Triumph unit-construction twins must include the following: The cylinder head must be of the pre-’67 “squishband” type. The maximum carburetor size is 28mm, and bikes must conform to all other Classic Sixties rules. Results in this class for 2020 will be reviewed.
The crazy part is that it’s almost like someone predicted this on November 11 in the comments section of the “2019 AHRMA competition rules changes” News item. 🙂 🙂
