Took delivery of my 2021 Ducati Supersport S yesterday. Fit and finish way above KTM RC390, should be based on price differential. The one thing I didn't expect was the ease of turn in, feels as flickable as KTM, and far more stable in turns than KTM. Ducati much more confidence inspiring in turns (and I doubt electronic aids have even kicked in at this point). Fueling much more spot on than KTM, perhaps a bit of surging at steady state speeds, with KTM I found a tune an absolute necessity. And then acceleration, while KTM was fun, Ducati is a rush, the way this thing is geared and power band made for street riding means you have near full torque at lower rpms. Seating position is totally spot on, probably 20% more sporty than a standard bike, on KTM I"m cramped up.
And then aesthetics, beautiful from any angle, real cohesive look with all Ducs, nothing looks out of place (exception of the rear fender, as with all bikes, looks like some added on appendage, and even here Ducati does a relatively good job). Rear fender will be gone today as New Rage Cycle fender eliminator here.
Anyway, at my age likely last bike I ever purchase, best enjoy while I'm able.
