  2. Same as most bikes I’d have thought: 20 and 25/30 depending on type of use
     
  3. Yes , it’s just the top out spring changes free sag so wanted to check

  4. I have a ttx shock, just fitted, never had one before so interested to know too now :upyeah:

    I’d call in @andyb, he would know I’m sure, but I think he’s flounced somewhere else ;)

  8. Thanks for that. So sag the same as normal
     
  9. It's a good starting point and you can adjust if you feel you need too.

    Suspension is like most things, in being a compromise. What you improve in one area is going to have an effect on another.
     
  10. I thought ttx had high and low speed settings?
     
  11. Mine doesn’t . Depends which model you have I guess .
     
  12. Depending on where the info comes from, there can be many conflicting specs. I remember looking into a lot of this years ago and the ohlins info for their products is often different to what you will find in Ducati bike specific tech literature. Oil weights and air gaps for forks was one case in point.
    None of it is set in stone of course, merely a guide to be the most useful reference point for the majority of owners.

    I found that when the rear is set up wrong on the panis at the track, regardless of rider sensation, that you will know quite quickly as they really will tear up and destroy rears. My first few track outings were very expensive on the rear rubber front :-(
    My 1098R was much easier/quicker to find decent base settings.

  13. I’ve heard that a lot Glen, with the 1199 being even harder to set up. Wilf always told me start with the rear: spend the money there as that’s where the business really happens. Slings and oil up front is often enough for most trackdayers, no need for expensive kit, but the rear needs more sensitivity in adjustment

  14. Weirdly I’m the opposite, as I need front end feel more than rear as I ride the front end .
    Guess it cone down to riding style and preference . I don’t brake super hard or get hard on the gas but I carry a lot of corner speed / lean angle . Probably not the best style for this type of bike and quick lap times , but I’m a 250 2 stroke rider and it’s my thang .
     
  15. I think Bradders is just noting that more folk find it easier to get an acceptable level of front set up compared to the rear.
    I had very little trouble finding a high confidence fork setting but it took longer to get a decent rear setting which frustratingly is also quite sensitive
    to temps/tarmac as far a tyre life is concerned.

  16. Surely if the stroke of the DU360 is 65mm you’d be aiming for 21-22mm sag when on the bike in gear? Just curious & always here to learn
     
  17. Possibly. Not set up this one before, just always use the same starting point.

  18. Front is where the feel is, but rear is what makes it track online, under or over steer is what I’ve been told by specialist hence money in the rear is better spent. It’s always what affects tyre wear the most.
     
  19. The shock may have a stroke of 65mm. But it goes through a linkage ratio and rear wheel travel is 130mm.
