Hi, I would strip the front re seal it ( very cheap..a few O rings, some oil), measure the free length of the fork springs and compare with original replace with new if there is any difference. The rear be very careful !!! I have heard tales of after market expensive shocks not lasting very long, your standard one has lasted 50,000 km, an after market at maybe twice the price would have to last twice as long. If you do go for an after market buy a rebuildable type..but how you re gas your damper in Africa..???? Nitrogen at 5 bar ???? I favour buying a low milage low age yam part for low money off E bay...throw it away when its knackered. Just my view you understand...
have fun Jimmy
