Tune, that's a great tank and the single is amazing. Looks a little flexy around the swingarm pivot.
A new thin wall chrome moly frame would be the way to keep weight down. CB160 frame is much lighter than a 175, but make a replica to suit and save more weight. Check out a Laverda twin frame for a similar look but stiffer. That might be harder to scale down and replicate, but it's neater than a CB in many ways.
That Joe Biden ( load of Malarkey) frame is probably the stiffest and lightest ( and simplest) design, but hides the motor which is way too pretty to put behind bars.
