Raising forks thro' yokes - SV650.org

16-06-05, 06:20 PM

Has anyone had experience of raising the forks through the yokes by a few mm to speed up the turn in to corners?

If so, by how much of the forks did you have above the top yoke?

Did you suffer any instability at high speed as a result? Is it worth doing?

The suspension on my 03 SVS is standard at the rear but the front has Progressive spring, 10 W fork oil and 26mm static sag.

I'd lift the back before altering the front, which I have on my mark I.
Turns quicker with just enough twitch to keep it interesting, weaves at 130 but how often do you ride that fast?

I am trying to avoid this route as it requires buying new dog bone, some spannering and some means of supporting the rear end.
Changing the front end seems and easier option - perhaps.

Cheaper option until something digs in the deck and cartwheels down the road

Mines been done, about 10mm I think, I dont know what its like as standard as the previous owner did this and I left it like it was rather than put it back to standard

My Brother has done this to his NC35 and he said it helped with the turn in a lot

I had mine dropped by about 14mm eventually with the seat up around 35mm. Some would call it unrideable

But I liked it. It made holding a clean line more difficult as the bike was very eager to change direction, but on the other hand it meant that even if things started to go a bit wrong in a bend it was relatively easy to make adjustements.

I've had to drop the seat until my leg heals up a bit more, it's only about 10mm up now... Strangely that didn't work well with the 12mm drop, after more experimentation I raised them back to 5mm down, which slows things down but makes for less erratic cornering.

Rob makes a good point but how many of us are going to be dragging pegs on the road? AFAIC that's just bad riding.

I dropped my forks 20mm and I've installed hyperpro springs and 15wt oil. These mods elevated my corner speed quite a lot, but this is mostly because of the springs and oil. I do like the crispier turn in a lot. If you like a nimble bike, do it.

20mm !!!!!!! youre brave, ive dropped mine about 8mm with new springs and oil and it makes a big diff, almost finished making my dogbones to lift the back, then listen to my missus complain, she will need oxygen up there.....

Well, considering my weekend/trackday bike is an Aprilia RS250, I guess I'm used to nearly vertical forks
