I own a Street Triple 675R 2014 - great bike, very happy with it however I weight 95 kg without gear and I believe I need a stiffer front springs. I found some springs option for older model but I have not been able to find any for my model. Can you please advise ?
You certainly will want stiffer springs. Im roughly 80-85kg and run significantly heavier aprings than stock (albeit for race usage).
If you know one go to your local suspension guy, they can advise you on spring rate. If you don't know one, check withe the local race organization. Check the track/race section for help finding one.
Since you used kg i doubt you are in the USA, but if you are, RaceTech is an easy to use spring rate calculator and will certainly have springs for a street triple. Any reputable dealer/motorcycle shop can swap springs for you.
