Good reliability. You get a nice rack from DRC I think that is billit aluminium made for the Z, once did a trip with Sidetrack, me on the Strom, he on the Z, did 600km for the day, 25km/l at 120kmh. He had a skaapvelletjie, never complained the whole day whilst i complained on the big seat of the Strom.
I know of issues on some with the waterpump, read the thread to speak to those okes. Mine never had an issue.
