Good idea! This bike was designed with maintenance in mind. Cylinders, ring & piston replacement can be done with engine in place!
I'm looking at replacing engine with more durable model perhaps. Bored & stroked Banshee engines can get similar power and last tonnes longer. But... output-shaft and sprocket is on wrong side of engine!!!
I may go back to my custom-framed Banshee-powered racer idea. A KTM RC390 frame has almost similar geometry to RS250R (which is still more aggressive). Perhaps start with Banshee-powered RC390 while I build custom frame. Current Moto3 NSF250R is modern descendant with 22.5-degree rake and 47" wheelbase!
Although that was more of replacement for RS125R.
