Our KTM Radiator Spacer Kit increases the degree of turn on 00-04 KTMs. The 2003 KTM 125 for example has approx. 65 degrees of unobstructed turning capability. With the spacer kit, you can expect a minimum of 75 degrees and up to 90 degrees if the black box is relocated. The kit also allows better airflow to the radiators aiding cooling which is particularly beneficial on four strokes.
