The DR 200 is an incredible little bike.
We bought one for my wife in April 2007.
As opposed to many Ag bikes it's a true DS in bonsai size. Very light (108kg), low enough for people in the 1.6m height range, and it makes the Yammie TW200 feel like a 125.
The 13l tank gives an excellent fuel range. (close to 400 km until dry).
The suspensions are very good for a bike of this class and cope very well on dirt roads.
The Trojan is the AG version of the DR200SE with an additional oil cooler (not necessary for DS / touring). It comes with cheapo chromed steel rims (Aluminium on the SE) and you will have to throw th three square metres of mud flaps and the right side stand into the bin as quickly as possible.
I also don't like the solid hand guards as they tend to produce broken wrists in an off. Rather go for flexible plastic hand guards and take one or two sets of levers as spares.
I don't think the DR200's frame is a problem at all as long as you load it properly and don't take the whole household.
Only weak points on the DR200 are:
The tiny oil volume of only 1100ml (it says 850ml on the engine). Once the engine uses oil you will have to check on a very regular basis.
The swingarm pivot bushes. Two pieces of fibre reinforced plastic c**p. They are soft and cause slight instabilities on hard, fast cornering (see what I do to a bike like that ;D )
Best to get them replaced as long as the bike is new as you will be able to reuse the hardened steel pivot spacers. I have fitted sintered brass bushes and grease nipples into my wifes DR200. You can also use the needle bearings from a Kawasaki KLR650 swingarm pivot
(any model, all the same)
