Hi all,
i will try to answer all questions in one post....
As for the OTR pannier system.
I used Touratech panniers on my bmw r1150gs (crashed, total-loss) and r1200gs (sold it last week after 47kkm), and the off-the-road panniers are same or less thick aluminium. I must admit that the the TT panniers feel more solid, especially without cover, not sure if it is the construction or the material. But with the lid on, the OTR rack and pannier mount system is very solid, but not more than TT. The fit and finish are certainly not metal mule (they are expensive!) or TT or Hebco&Becker level, but so is the price...
To be honest, i bought the OTR system from the website, and next time i probably would spend a bit more and buy Hebco&Becker panniers with it. on the other hand, spending a bit over eur. 600,- for a pannier system AND luggage rack of this quality is not a bad deal.
In my experience OTR need some improvement on the aftersales part. But the owner is an experienced TTR owner/driver. currently they develop a very nice XT660R rally version (big $$). But the perfect overlander me think.
As for oil consuption: zero, nada, nothing. Being a bmw 1100/1150/1200 boxer owner, this is really something i have to get used to

, bike has 5000km on the clock. So far i did some long highway stretches and some allroad/offroad tracks. No experience in very hot weather yet. Before i go i have a few weekends with long distances and some offroad tracks.
As for the tires: i had an off-road trip and got these worn out tires from a friend, don't know the make/model, but they are scary on tarmac

. Few weeks back i changed them for MT21's with heavy duty inner tubes. It was my first tire swap ever (bmw driver...) and it took me about 6 hours for both wheels, and three puctures in the rear innertube

. I really thought i needed to do this once before leaving. (lesson learned: there's a trick for everything and brute force not a good thing

)
Next time i probably get T63's, more durable, bit less on wet tarmac compared to MT21 (not from personal experience). I got the MT21's because i liked them on both tarmac and gravel (I drove with a group for three weeks in Peru on a XLR650, loved the bike!!)
Also not sure if i keep the heavy duty inner tubes, they are very hard to put in the tire, imagine this on a wet, muddy dangerous road somewhere out back.... need some advice on this, there was a threat a while back about slime stuff you can put in the tube. I need that so i can always keep on going and go to a save place to repair tire (good advise from a friend and experienced overlander).
I bought the bike and tires
before i decided to quit job/ lease my appartment and GO. Wanted to use it initially for the occasional all-road/offroad trip. Turns out that the bike isn't a bad choice.
(at some point i probably regret the kickstart only....) but i see no point in start all over again for an XT, f650 or KTM lc4 Adv. and it saves a lot $$ in parts, shipment, insurance, carnet etc.
Too bad honda XLR650 (first choice!) or Suzuki DR650R are not available in Holland.
Cheers,
Sander
