DS what?
monster multi or ss?
The 800 was not ever a dual spark and has 2 different type swing arms.
the multi was a single sider except the 620 model
the monster and the sport have different swing arms to each other as the suspension is totally different in the way it is fitted.
the monster non-single-sided ones are 90% interchangeable if off the later bikes from approx 02.
