KTM RC250R Production Racer in detail

The KTM RC250R is probably one of the best if not the best ever 250cc production racer yet. It may not exactly be the easiest motorcycle to get your hands on but its very close relation to the KTM factory Moto3 bike makes it worth every penny. Only 67 of these machines will ever be made and of these 40 go up for sale, 27 of them will go to the Red Bull Rookies Cup.

“The differences (between the RC250GP & RC250R) come through some little details” says Head of KTM Customer Racing Wolfgang Felber. ”The GP bike for example runs with the regulation enforced Dell’Orto electronics unit, has a different Akrapovic exhaust system, magnesium wheels, and modified brakes as well as WP factory suspension parts, which help to save some more weight.”
