inverted front forks?

  1. I know inverted forks look cooler, but what other pro's and con's are there?

    Not every motorcycle has inverted front forks, so what are the advantages?
  2. dont know but would like to

  3. Less unsprung weight = more responsive/better handling.
  4. the way I understand it, the one of the benefits is less mass to move up and down...

    also, it's the new hawtness, so you have to have them or you're a noob.
  5. I seem to have more seal problems with inverted forks.
    Not horrible but it seems more often than with "standard" forks.
    Maybe a marginal seal will start leaking sooner.
    Easier to get rock chips on the tubes.
  6. All forks (conventional or inverted) have larger diameter outer tubes, and smaller diameter sliding tubes. I'm fairly certain the main benefit of installing them on a motorcycle with the sliding tubes at the bottom is it allows the larger diameter tubes to be held in place by the triple clamps. By clamping the larger or "stronger" tubes the entire assembly is stiffer with less deflection over bumps, turning, braking, landing wheelies, etc.

    What do I win?
  7. less unsprung weight and the forks flex less at the triple clamps
  8. I'm pretty sure the primary advantage is, as stated above, less unsprung weight. This allows the fork to respond better to irregularities in the road surface keeping the tire on the ground better.
  9. Ding! Ding! Ding!...You win an all expense paid trip to your kitchen! Grab yourself a beer!

    That is the main advantage of inverted forks.
  10. Since I'm in no danger of wading them up in a stoppie or of running down the Track Lizards anytime soon.....I'm not too worried about trying to look the part either.
  11. The main benefit of inverted forks?

    The fork bushings are dramatically further apart inside inverted forks making them much more stable. What alot of riders feel as "less flex" may be slightly less actual tube flex, but more importantly, less slop between the upper tube position and lower tube position. Bushings also last longer.

    At least, that is how it was explained to me when I attended a Race Tech / GMD Computrac seminar.
  12. Hmmm... I kinda like it when a thread turns into a learning experience.
  13. Inverting your forks make them stiffer, like this site makes me.
  14. Well put! :scared
  15. This is PNWR record, 12 posts before we headed off into the weeds.... :angry7:

    All the reasons I've heard have been noted, less flex, less weight, plus, if the racers use them, they MUST be good! :thefinge:

    Flexy forks on a flexy bike with 30 HP can be very exciting!
