i've got a 07 Triumph daytona 675, so far it has a 520 conversion, aluminum sprockets, aftermarket gearing, leo vince,steel braded brake lines, tune ecu tune, slicks, track pads, tuned stock suspension typical basic stuff. I was thinking about having a local suspension company revalve and respring my shock , the front feels decent, the company i would be using is really good and they even have a shock dyno to test with. but i was wondering should i focus on buyin some differnet rear sets first, or anything else before i do suspeision mods, not really looking for more power. im comming from racing off raod and i know in the dirt suspension is everything, so thats my current assumption with pavement so any advise would be greatly appresicated. thanks
i would go with the suspension mods first, Often stt has superbike suspension at trackdays and you could have it done while at a trackday,the bonus would be having the man that built it tune it . See ya at CMP.
Great Bike.... Yes you have lots of options... Is it a 675 Rwith the Ohlins goodies? Either way as Jim mentioned its best to get it done trackside that way you can get support and have adjustments done that day.. Ken at Superbike Suspension is at most of our events and will take appointments so you wont lose any trackitme.. Hope to see you out there.. Marc
Suspension comes in stages: 1) Have what suspension is there now tuned for you by a pro, usually done trackside. 2) Sprung for your weight and tuned for you. 3) Fork revalving and a race shock, sprung and tuned for you. 4) Fork Cartridge kit and a race shock, sprung and tuned for you. Increasing money for diminishing returns. Understand that ANY change from stock is so huge that later, more expensive mods will never produce such a shocking change. #1 makes a HUGE difference if your suspension is off. It's the difference between balance and a bike that fights itself front to rear. #2 is also a radical improvement if you're not the size of your stock springs. #3? If you can RIDE, you'll be hard pressed to ride less than that. If you're still learning, maybe you won't realize the full potential but it's there to grow into. 4? Once a skilled rider has gotten used to 4, anything less seems dangerous. It's all about your skill and your expectations. Note the comment in #1. At any level of suspension modification, if it is not properly set up, you will have an unbalanced bike that fights itself and you. A well tuned stock suspension would outperform a $3000 race suspension that is out of tune. Your friend mentioned Superbike Suspension. That shop does excellent work.
+1 on what K3 said. That being said I purchased a 2007 Daytona 675 around Christmas and have been working on getting it ready for the coming year. Based on the research that I've done there are a couple of things to note. The shock is over sprung unless you are a 250+ pound rider. The forks are under sprung unless you are in the 150 to 170 pound weight range. Either way to set up the stock suspension for your weight you will likely need new springs front and rear. Another thing to note is that the stock shock is not very good. The compression adjuster only tunes the high speed compression damping and has little to no effect on the overall compression damping. This has been proven on a shock dyno as well. I've been told that revalving the shock doesn't do much to help the performance either. I think enough other people have told you what steps to take with your suspension so I won't beat a dead horse. I'm replacing my shock with an aftermarket unit that is set up for me and having the forks resprung and revalved. You asked if there were other mods you should consider before suspension and I would say no. After you get the suspension dialed in then you can consider putting on an after market steering damper, race body work, and rear sets. I've also already replaced my stock steering damper as I didn't feel the stock unit provided enough damping. The rear sets are last on my list and until I have an issue dragging my pegs I probably won't bother.
I'm not familiar with the 675. I usually end up with racing rearsets when I do a build. In truth, I'd love to save the money and skip them but I tend to fold the stock pegs as I move around, so I end up needing the aftermarket stuff. Absolutely HATED the stock pegs on my current GSXR, as they would fold back and drop my inside boot right off. Call me "Mr. Big Feet..."
