No, it's not necessary. I've had bikes with good working suspension though, so I am picky. I also commute, hit the twisties and track days on my bike. I can't buy a dedicated track bike so my Current bike has to do everything. The money spent on my suspension is worth it for me. It will be for a lot of people and for others it won't be. Just don't have the assumption that if you are just commuting in it, it will all of a sudden handle terrible because it's not an upgraded cartridge kit. I will say though that weather you have cartridges or a basic damper rod fork, it's always good to have the correct springs for your weight, correct preload and sag set up.is this necessary? is the stock suspension that bad?
I ordered the same kit from Jesse. Can't wait to get the new suspension. Signed up for my first Race Academy session out by my local track for the end of August. So hopefully I get the suspension delivered and installed in timeJust got a damper rod kit w/ springs/ Norton race spec. shock from Jesse at www.yamahar3racing.com
$824.95 w/ free shipping. Set up for your weight and riding style.
Takes a little work to install but it is worth it.
If you have a limited budget, these are the way to go.
btw, I don't work for Jesse.
