You'll need a higher viscosity oil.

Thicker oil in the front. Or consider getting some USD's

I'm sure someone on here will shed some more insight.

You need stiffer springs, thicker oil just increases damping ,Yamaha TT250/350 springs  fit and are a bit stiffer .

Aye maybe for off roading abuse bob, but for just road use and Sumo'd I reckon you can get away with adding thicker oil.

Do the 125 forks have a schrader valve in the top like the DT200 ones ? This enables you to add air to the forks to stiffen them a little , you only need 1 or 2 psi .

No mate, but is that something that could be added and done with a tap set into the caps maybe?

thanks for the help lads nev i was speeking to you on youtube about your dep can haha, yer i thort thicker oil, i have some questions tho, fist are both sides oil, 2nd if so there are 2 bolts at the bottom, is it that you take them off oil comes out into jug and then put them back in and then take off the two top caps and poor the same amount off thicker oil in the top. and 3rd NEV you think 15W is good to go for or sall i go stiffer like 20W. 4th any good oils for me to go for thanks.

Ayup there Live2ride, aye I remember you now, good to see you've joined the forum mate. right then, you'll need to undo the allen bolt on the side at the bottom of the fork to drain it out, and you're right with the top caps to fill it back up, I'd try the 15w oil to stiffen up, as 20w would be a tad too stiff in my opinion, but remember if you find its still needing to be a bit stiffer after using 15w oil, get equal parts of 15w and 20w and mix to gether in a jug/container, this will give you 17.5w oil if you get me, same if you find 15w is too stiff, mix 10w and 15w oil in equal measures, that will give you 12.5w oil.

Aye I reckon so, or Halfords if you need in a hurry. Silkoline, Castrol, Motul all do decent fork oils.
