I'm 19 stone in all my gear so I'm thinking of changing the springs front and back and having a full rebuild done. Anybody here done similar and agree that the cheap solution is a valid one and will improve the bike. FYI bike is standard 14 plate 1199, and springs will be K-Tech Andy
In theory yes. The thing is though and it’s worth remembering that much of it is preference/riding style (braking characteristics especially) and that the ‘book figures’ are based on someone of your weight at race pace .. meaning likely too hard for most people. I run a fairly hard rear (woheyy) as I like the exit support and a pretty soft front end with some preload wound in usually as I like a good amount of dive to get her to turn. I find the softer sprint with preload gives better feel for me. On track the general rule of thumb is to run as soft as you can get away with at the front.
Changing spring rate to better suit your physical circumstances (and consider changing the viscosity of the fork oil) is, as I found, a very cost effective first step which could solve your issues with handling as it did for my girlfriend’s Diavel. KTech are not the only source of good quality springs, I found these people very helpful,http://wilberssuspension.co.uk/ Andy
Thanks for the reply, in definitely no expert on suspension but it just feelings soft and not composed however so I'll leave it in the hands of KRG Racing and hopefully he'll work some magic
Andy the lad that's doing it is a K-Tech technician so that's why I'm placing my trust in him and hes also doing the 7500 service for me. I'm just hoping that I'm not expecting to much of a difference, only time will tell
Did the change on the Diavel (Marzocchi forks) and the difference was night and day. Finally got permission to play with the Ohlins rear shock settings and managed an improvement that made her smile. Good luck. Andy
Surely if the guy who is working on your bike works at Ktech...then he must be in the best position to advise on spring weight and sag based on you and your biking needs..
OK then, Surely if the guy who is working on your bike is setting up race bikes, then he must fully understand the ratio of free length bike weight bike and rider weight to formulate your sag which ultimately dictates what springs you require. If you are going to bother to change springs then you might as well get it right specifically for you. Think of all the different riders a std generic bike has to fit to , so you are correct in changing it! I know ohlins has a chart that can identify a working area of a specific spring weight to rider weight. Measuring Sag is the recognised formula for getting the correct spring for the above. If at your gentle 19 stone you will need heavier springs front and rear you need to work out whether the comp and rebound damping will still be effective with such a heavier spring or that will need a revalve too. This is often done at a specialist like ktech with a shock dyno. find out what the std spring rate is find out what spring you need to achieve sag and how bigger increase this is over std find out if this is too much of a step up for the current valving So to answer your original question a cheap fix might not work
kin el....is it 3 weeks because you are having something else done, 3 weeks because you are going away or 3 weeks for them to change springs in forks and shock? seriously have you considered using somewhere else?
claim down, claim down. I'm off to Cancun so away for 2 1/2 weeks but it'll effectively be 3 weeks by the time I pick it back. Shes also getting 7500 mile service
does the guy doing the service want to know how much oil to put in it...... and cancun is not in Florida..
LOL the Florida reference is from when the kids were younger we used to holiday there as we found it easier than running around a pool every day lol. Kids are older so we're chancing take them somewhere posh haha
