I have two friends who’ve recently bought the new Tiger 1200s, both very impressed with them. When the time comes it’s definitely one to try. I rode several of the previous model and despite what a lot people ay about it being lardy I thought it was a lovely bike.
I was surprised how good it was! Feels lighter than a GS, more nimble. Better brakes (the GS isn't lacking with the Brembos but the higher-spec brembo fitted to the Tiger were very good - it has linked brakes like the GS too). The "usual" rev range of 2500-6000 rpm the Tiger felt awesome! Seating position very similar to GS. It's a bit higher geared than a GS too, so 70mph is about 4000 rpm IIRC. Some reviewers say it's vibey but that was not my experience unless going over 6k revs when the thing howls like a banshee and the horizon gets nearer very quickly! (not as frantic as a 1000XR of course!!) Actually thinking about it, the Tiger felt like a love child of an XR and a GS
Main negative for me with the Tiger is the crap luggage. I like the way GS panniers (vario) just lock on and off so easily, and don't leave hideous scaffolding when the panniers are not attached. No similar option for the Tiger sadly - you're stuck with hideous (like GSA) scaffolding making the bike look "unfinished" without panniers. The Touratech ones look the best option, and they have some kind of QR scaffold option I believe, so at least you can take the scaffold off the bike for most of the year!. I only use panniers on longer tours or weekends away with the girlfriend. When solo, for one or two night trips I use a 32L Enduristan duffle bag on the rear seat...
Another positive seems to be the dealer network. More and more BMW dealers seem to be attached to car showrooms, and I feel I'm just seeing the "corporate bollox". The Triumph dealers near me are genuine bike shops, and I (personally) find that a positive, refreshing change!
