Front Suspension

My bike has 21,000 kilometers on it and I'm feeling the front suspension a little "soft". You know, when you apply the front brakes and the bike leans forward (a lot).
Do you think that if I change the oil for a thicker one, I will make the suspension a more firmer?
Does anybody have experience this or do some simple mods in their front suspension?
Thanks!

how much do you weigh? may be a good idea to respring for your weight as well as modifying haydraulic viscosity

mmm... I'm 210 pounds.
I know this bike has a soft suspension but with the years it become softer...

Springs control the weight, damping controls the speed at which the springs compress and extend.
Simply replacing the OEM oil to the stock height will definitely improve the response, but as you find the softness an issue, yes, you would probably appreciate the next grade up as the oil ages and thins.

21000 kilometers isn't too early for the fork oil to be needing replacement. It gets pretty contaminated and watery. A higher weight oil wouldn't hurt either.

A big part of the reason for the soft suspension is the progressive rate springs. Unfortunately, those springs are a big part of why the bike dives like it does under hard braking. Upgrading the spring rate and going with constant rate springs is probably not a bad idea given your weight, and not very expensive.

To help with front end dive Ricor Intiminators are your best friend.

Last year I was frustrated with the front of my DL. When running over things like manhole covers the vibration would reverberate up through the bars. I know the forks are antiquated technology and was going to pull the trigger on some fork internals to help smooth things when I talked to a buddy that has a DL1000. HE had talked about a fork brace doing wonders to help the front of the bike. I ordered one and he was right. While the front end still isn't Ohlins the fork brace made the front end light years better.

For the record I also have a fork brace on one of my DR's and there is no discernable difference w/ or w/o. But on the DL its night and day.

My new to me 2012 650 would really dive when I hit the front brake. I'm about 190 pounds geared up. I installed stiffer springs and emulators and went to a heavier fork oil. Made a huge difference. Also upgraded the rear at the same time. Whole different bike now.

Another vote for intiminators and their recommended fresh oil. My 2012 650 23,000 miles that fork oil was nasty. I'm 210 also

Fresh heavier oil will slightly slow down "brake dive". Heavier springs will be needed to really help that. These V STroms have a poor front suspension to start with. Adding cartridge emulators, proper rated springs, and the right viscosity oil is worth all the money spent on these.

There will always be brake dive on these, that is part of the geometry of the suspension. But it can be reduced and much more control maintained when the modifications are made.
