The RAVE II report did not have the MK0 but it did have 2 MK2 bikes. The test is dated June 13th, 1963 and is the last test that I found on the Nethercutt bikes. The mule is on page A1 and the MK2s are on A-5 and A-6. Looks like the 30 year old mule showed up late and missed area A but did better in area C and the swimming part than the MK2s did. The test was held at Tomahawk Hills Pontiac, Michigan.
