That because the tyres are then doing less of the absorption duty and therefore placing more energy directly into the suspension.
    You have a top reputation as a suspension specialist on here. What would your advice be? Given the symptoms is it likely that I could get any old motorcycle shop to look at it or would you recommend heading over to a specialist such as yourself or Shaun up in Auckland?

    Suspension has become a specialist job as the industry training for motorcycle mechanics has not kept pace with the times in respect of suspension. Thats a stark reality. It is clear that at minimum it needs firmer springs correctly preloaded and attention to oil viscosity. Ideally Race Tech emulators to sort out the remaining 50% of the problem, poor hydraulic control.

    UPDATE: Well it turned out to be the front forks causing the problem in the end. I took them into the shop and had them disassembled and inspected and we found that they must have been leaking for a while as the oil levels and condition were low and poor, plus the forks had pitting in the travel area. So the forks were sent out of town for re-chroming and then reassembled with new seals and a heavier weight oil (the standard oil is about 7 weight from memory).

    I just got the bike back today and put some kms on it and it feels like a completely different bike, no more bottoming out and I feel a lot more comfortable riding on the road again.

    Many thanks to Steve from WOT Motorcycles Taupo - you were a big help mate and I'll definitely be paying you a visit in the future.
