Front End Dip

Do seals and oils.

Put a spacer atop the spring , this will stiffen up the front.

You can adjust the the spacer thickness to check out how much stiffer you need to go.

Cheapest way , you can use plastic pipe of appropriate size.

 

New oil already improves a lot.
I would start with that, and the seals while the tubes are out of the bike.
A spacer can be added later. It's just sometime difficult to push and put the tube cap in place.

 

Heavier grade oil will help too.
If standard is 10 grade go for 15 or maybe even 20 but I would go 15 first

 

Yes I usually go for heavier oil. And yes I have many times in the past added equal spacers to the top of the spring. But if you intend to track day the bike get on the oilins site and see what they say or maybe even find a cheap set.

Be careful if you go the way of putting spacers in because it’s easy for the spring to become “coilbound” at its full compression and that is something you definitely want to avoid. Cheap way is to use spacer(s) and thicker oil, next have the bike set up for your weight and intended use with premium products (Maxton etc) or change to something like Ohlins set up as above (best have deep pockets).

 

Springs are going to be well past their best at that age and mileage, the bike was probably sprung for an average 80Kg rider when new.
You'd definitely benefit from replacement springs and more so from heavier duty ones. 0.90kg/mm matched to decent hydraulic control would be far better. Possibly even 0.95kg/mm springs.

 

@Chubzilla , any new spring would be a slight improvement. The bike hasn't done enough miles to be seriously degraded even though it's 16 years old . Additional spacing might be enough, even with new spring's to get less compression under heavy braking. Stiffer spring might be attained by extra coil's/length , and then you need to adjust spacing anyway.

 

I've used K-tech (Derbyshire) for springs in the past, they list a set for a 2004 Daytona as measuring 37mm diameter and 375mm in length and available in different spring weights. If you decide to upgrade seek advice from their experts.

And there is Hagon they do a great range also progressive.

Chubzilla.
No most people who build pro springs do around your weight and style of riding. And they do improve the handling and take the rough out of the ride. But good strong standard springs are all right as well.

Springs will with age sag , if you leave any vehicle sitting on its wheels , over time the springs will settle to a new height.
If the vehicle is loaded up whilst it is sitting still it will sag more.
With motorcycles up on centre stands the front Springs carry/take the load.
If you lift both wheels you protect tyres,springs and bearings from ageing.
During my Army career , I was posted to 21 Supply BN. They stored trucks for many years , all were supported off their wheels ! Suspension in fully unloaded position.
