I passed my test back in September and bought an RD04 Africa Twin. There is more than enough power to do anything you want with this bike. I also have a CBR600 as a second bike. I will always take the XRV over the CBR as it is so much more fun to ride.
I have done 5000 miles since passing my test and the bike has been faultless. It even survived a nasty crash after sliding on some black ice near Exeter and only needed a brake lever after going 250m on its side down the road. Picked it up and started first time.

Two up, it is fine, though be aware that the seat is one long seat and your pillion can slide about a bit!
I changed my screen for a tall one, and added some semi-off road tyres (mitas e-07) which makes the Twin into a fantastic off road bike. Mine kept its own against a CF250 up the devon greenlanes, and despite its weight will match anything on the rough stuff!

There are LOTS of superb accessories for the RD04 on german ebay which is good, as it seems that the likes of Touratech have forgotten that the original (and more off-road biased) 650 (RD03) and 750 (RD04) Africa twins ever existed which is a pain!.

I plan to change the gearing a bit with different sprockets to make motorway mileage a bit better. Mine manages an average of 34MPG which is ok but not as good as the later RD07/A.

nothing else to say ,its great bike perfect to go to places Like Africa ,Asia also to use it on the high way all over the world ,the engine can do 60000 miles easy just change oil and regular service ,

Love this bike. It gets me to where i want to play offroad and back again

After riding road bikes for 18 years I bought this bike for a West Africa tour and now I'll keep it for the rest of my life.
