Maybe try reducing the rebound damping a few clicks? Could be mean end packing down/staying down causing front end head angle to go slacker = wonders off line or feels knife edge.
Had that once when borrowed a mates triumph Street triple, he's heavier then me, so had taken some preload off but forgot rebound and thought it handled fairly horribly at lower end of 2nd gear type corners, few clicks less and felt more confident at the front.
the bike is brand spanking new Thruxton RS (which isn't a beginner bike, but I consider myself fully qualified to own it and learn on it for a lot of non-idiotic reasons). Whether it needs to be set up better is something I've considered, but skill is 90% of it.
1st gear low speed lean maneuvers which require clutch-brake modulation at near full lock are not hard for me because of extensive manual transmission use in cars and decades of MTB and trials riding.
its second gear pulls out of turns that i'm talking bout. 15 mph-40 mph type of things.
I did go through the suspension according to internet and triumph manual and so it cannot be too far off.
I did check my tire pressure and found it down from the recommended 36 PSI to about 28 and i thought i could feel it a bit when i tanked it back up, but that was probably mental.
I think it mostly boils down to what @Jung @Ramsaye and others said: not looking down the turn enough while letting the rest fall into place...
