Doesn't seem to be any service requirements in the provided manual for the front suspension. Even my bikes back in the seventies, R5F Yamaha, GT550K Suzuki, Yammy XT500's had specs. So why not these big weapons. I have nearly 60k Klms up and sort of think that something should be needed. I'd like to be able to pull something to bits on it! Has be pretty much service free, apart from usual to this date.
