I had a 2002 520,
it was sweet.
So, I have a new 14 front sproket and a M5B about to go on.
And chain glide, rear spoket (48), lower slide thing ( I had little wheel from a 98 cr500 on this whole time ), chain, needle clip just dropped and newly cut plastic around the seat ( with damage ),
I'm just asking for it on these trails out here.
And my 2002 520 MXC went from 2002 till 2009 like full speed on and off road almost every day.
with daul sport tires a lot of the time.
