IMHO the poorest part of the bike is the stock suspension.
Many have fitted aftermarket fork springs with claimed improvements and a fork brace helps to improve handling (but not ride quality...)
I recently bought & fitted Ricor Intiminators to the otherwise stock forks which greatly improved the handling along with an improvement in Ride quality.
It still leaves a bit to be desired ride quality wise & the rear shock struggles to cope when pressing on, particularly on poorer road surfaces.
