    Greetings from another new member. Has anyone found a decent suspesion set up for a 09 (old model) other than original handbook settings , i am finding that on bumpy , poorly surfaced roads (thats all of them round here) riding as they should be ridden , some of my lines are interesting , to say the least ! Any ideas greatly appreciated . I`m about 6' and 14 stone, and ok i've already heard a diet would help it go round corners , but no chance ! Otherwise im loving my first Triumph. Cheers

    Hi folks, in answer to your posts,your right , mine is one of the discounted 08 models registered in 09,im a sucker for a bargain , but maybe i should have bitten the bullet and paid the extra for the 09 model with the improved suspension ? has anyone here owned both models and how much better is the new one ? As to fzr login , i've also got an original 1987 1000 genesis which i've had for longer than i care to remember , so i should be used to the odd moment mid corner , with a 22 year old rear shock !

    I owned an 07 in scorched yellow and now have an 09 in red, and yes the new one is better, only marginally in the hands of a rider such as myself but for faster riders however the improvements may/would be bigger. One of the big differences is (unfortunately for you) the suspension. Its more adjustable with high and low speed compression. Im much more settled on the newer model . Here is a link I found on another site which "may" help in setting up, but I think it depends a lot on your riding style :geek: :)

    Hi Terry, welcome to the forum, I'm in the 14 stone club and apart from
    the occasional jolt can't say I find it a problem and have not made any
    adjustment from factory settings, maybe that may change as my riding
    style improves :)

    'Must agree, I'm a 13.5st plus leathers etc so over 14st kitted out and i've not tweaked the rear suspension, it doesn't jolt me around much at all and no where near as much as my old zx6r did and that was after the suspension set up.

    So us "meaty beaty big and bouncy" bikers are the perfect match for 675 :lol: :lol: :lol:

    PS whos album is written above :?: :idea:

  11. TRY RIDING WITH THE THROTLE PINGED OPEN ALL THE TIME :eek: :eek: :eek: IFIND THAT HELPS :D :D :D
     
  12. I had exactly the same problem as you - the roads in East Anglia are so bumpy that it made the Daytona difficult to ride. So I set up the suspension to suit me, on the road. There's a post above to setting up the suspension that is correct, but a little complex. It focuses on damping settings, and that's the last thing you touch.

    First you have to set the pre-load, or Sag, front and rear. It's easy to do with a mate. Ohlins apparently know a bit about suspension, and their manual for their D675 replacement shock tells you how to do it (no different to the advice previoulsy given, just in a clearer fashion, I think). See:

    http://www.ohlins.se/Products/OwnersMan ... 241-02.pdf

    I'm prepared to wager a small bet that you won't be able to set up the rear sag properly for your weight. I know this because I'm a bit of a porky bas***d and the rear spring is way too stiff even for me. Also, there's a hint in the Owner's Handbook, page 103, where it states that the maximum payload for the (2006) 675 is 195kg - that's 2 porky bas***ds! Triumph will have had to fit a spring that can cope with a pillion, so it's not going to be right for just you. Forget about playing with the damping settings until you get the sag right - you're going to need a new spring. I got my spring from these people in the US:

    http://www.racetech.com/

    There's a handy little calculator that tells you the spring rate for the your weight - I found it spot on - the sag came in right on the money (both static and rider sag) once I fitted the RaceTech spring. You may be able to get springs in the UK. Fitting the spring takes 30 minutes and doesn't need a spring compressor.

    Now that you've got the right spring for YOU, junk the pillion seat and the pillion footrests. The bike looks so much better and its a dog two up anyway - no fun for either of you. The pillion's weight is just in entirely the wrong place (unless you want to save on front tyre wear).

    Once you've got the sag set properly, you will find the bike transformed. If you thought it handled well before, be ready for enlightenment. Now you can play to your heart's content with the suspension damper settings.

    In my bike club, we run 2 or 3 suspension set-up workshops a year - one of our members is a bike mechanic and ex-racer. After a correct set-up, everyone is delighted at how their bike is transformed. Its the one simple thing that you can do to make you go faster (much, much faster than new cans or a Power Commander).

    Finally, the last piece of advice that I offer is to burn out the stock tyres this summer. They're excellent when hot, but they don't warm up easily and lose heat easily - they're designed to be riden fast - continously. Come the autumn, on cool damp roads, you'll think you are riding like Torville & Dean!

    Hiya again,many thanks for the suspension set up links , i write this from my hospital bed......(not really) , seriously though , having read and reread the instructions, which incidently say basically the same thing in varying degrees of understandability (is that a real word ?) ,i checked the setup of my bike , the front preload came bang on both static and rider sag but the rear needed more preload to get within the recomendations , i know these are only guidelines and not set in stone but you gotta try ,weather permitting the ride to box tomorrow should tell me if im wasting my time or not, i will let you know.

    Hiya, i live just outside chichester,west sussex ,close to whiteways at bury hill , that A29 / A24 should give my suspension setup a decent test .
     
  16. To Dunx675,
    Good post, however I looked at the racetech site and found the calculater but it may as well have been wrtten in japanese as Im a complete dummy regarding suspension settings. :oops:

    Im not exactly small but as far as I can work out the springs I would need are less than the softest they sell :?

    Does anyone know anywhere in the North West that I could take the bike to?

    Thanks
     
  17. Interesting about the shocks, but i can only agree about the tyres - they are a touch lethal when cold.

    Came out of a mates earlier, we had both ridden in (him on Sportmax's me on the Supercorsas) and the front end run wide as we pulled out. Scary. At least i realised - got them up to speed fairly quick though - and they are good when warm.

    Looking at BT003 RS's next i think :)
