Question Opinion on swapping in 2009 D675 forks

Hi there,
Looking to change the the stock suspension on my 2010 street triple. I'm 75kg without kit, so I guess 85kg with kit, bike is for commuting / urban road use.

I believe the best option is to get the internals upgraded on the stock fork but there are a few logistical (and cost) issues with this option.

Instead I have an offer to buy forks+calipers+master cylinder from a 2009 daytona 675 to put on my 2010 street triple...are there many folk out there running these stock Daytona forks - is this likely to make a significant improvement over the original forks or is it just marginal.

Any advice is appreciated

Thanks
Austin

I weigh the same and I loved the stock 2nd gen front end. Big improvement over your forks, just give them some 5 wt oil. Stronger brakes too, although I found the Nissin monoblocs were a little draggy and needed cleaning often.

Thank to the reply.
I've read that the d675 forks are quite stiff. Did you find them ok on crappy/uneven roads?

Yeah they're pretty stiff but the range of adjustment is decent. Fortunately, I never found any really bad roads while I had my gen 2 in California, but I wouldn't want to ride any washboard roads for miles on end. Keep in mind they're forks from a sportbike and behave accordingly.

I think you would like the change, personally I think the brakes alone would be worth the swap. But the forks aren't too bad on rough roads. It's the shock that is bad on rough roads IMO I have mine on factory settings and could definitely go softer so I doubt you would be unhappy unless you are expecting tourer ride comfort.

I'd buy the new forks/brakes and put them on. I run Daytona forks w/5wt oil on my 2010 Triple and I'm only about 5 lbs heavier than you. I have to back out the preload pretty much all the way, however.

Keep your stockers to return the bike to stock before selling. You'll probably recoup most of your investment as long as you don't overpay for the used forks.

Agree with everything said above, as I've been down that same path. Easy swap. 😊

Took the plunge and bought the forks + brakes.... will report back when fitted.

Glad you mentioned this as I think the previous owner put 10W oil in them - will swap it out to 5W before fitting

No harm in trying out the 10W to see what you think. People also often change to a slightly larger air gap (110mm) to cut down on harshness.

Would 5W be better for road use to reduce stiffness / damping?

That air gap setting of 110mm, is that up from 89mm stock ?
