Face it, if you want to play on real dirt where you regularly drop a bike, roughly 300 lbs is the threshold. Even the 315 lb. DRZ400 gets tiring if you need to keep picking it up. Yes, I wish MamaYama made the Tonere 100/200/300 lbs lighter. It also needs a good skid plate and bars to protect the sump and fan. But then so do most adventure bikes. Now that the Super Tenere has been out for 3 1/2 years, clearly Yamaha made a decision to take the weight penalty to get reliability in a bike that has been beaten by the worst of what the Aussies and SA owners could dish out. I find it odd that the Yamaha accessories haven't been adequate, but the aftermarket has provided everything needed.
Folks who felt the Tenere needs more power have been satisfied with the ECU re-flash. It's become a fairly common mod, so even while I don't feel the need for it, the option is easily do-able and the $400 is affordable.
Even so, I've single tracked the Tenere, run it up loose rocky trails (TC off), down loose rocky hills (ABS not inhibited, unlike the oil head GS), and tossed it in sand. The worst that's happened is I had to bend the shift lever out from the engine case. The Tenere's been neck & neck with the oil head GS in every way and WAY ahead in both TC & ABS. Both are smooth and the ABS doesn't need a switch. If you still wanted to disable ABS, you could just run it 20 seconds on the center stand, but the Tenere ABS won't leave you without brakes on a loose downhill the way the GS will in the first place.
The thing that BMW does better is smoothness on the highway. New 2013 Teneres can be found for $11,995 and just how much is that ride and roundel worth for the R1200GS or GSW? This is real money and MY wallet. After doing an Edelweiss tour with 4 new R1200GSW's in the group, I was really impressed this summer and still am. If you can swallow the price and are willing to put up with new model issues, the GSW is a nicer bike that I really want to like. While there are a couple photos of broken GSW steering heads looking like choppers, at least one is post-accident, versus at least 4 of the F800GS. The Big Money Werks seems to have solved the breaking final drives, but with 3 recalls, start complaints, and other issues, I'll echo my Beemer GS buddies and let somebody else be their beta tester till at least next year. As miles pile up flawlessly on the Tenere.
We have both a DL100 Strom and the Super T here and the Strom feels like an antique when moving from one to the other all day. The Tenere is FAR and away better off-road and on. Slabbing with cross winds make the Strom into a fatiguing workout machine. And I'll never go back to a chain for commuting and touring.
