just removed my rear shock and sent it to Denso for a service, 5 day turnaround, great service.
Shock removal isnt difficult just a bit tedious removing so much to allow the shock to clear the front area of the mudguard for removal.
If considering it my 2p worth.....
take the wheel and silencer off to make access easier
dont use cheap or worn torx bits as everything is very tight, a 2 foot breaker bar going easy takes the shock bolts out with no heat handy enough.
before refitting, knock the bottom swinging arm bush back in flush to save a lot of beating and swearing.
