Testastretta Multistrada... YES PLEASE
As for the current MS and how it compares, well i'm still running my multi in (1st service on Thursday) so will be better qualified to talk after i've done a few more miles but going of the run in demo bikes i'd say you would really notice the power difference at 3 figure plus speeds where the 4 valvers would run away and hide. There is something about the 996 when it starts flying it feels brutish in comparison to the multi.
This may sound negative uptil now and i did ask myself why am i getting rid of the st4s for an underpowered slug, if you just read the specifications; but i am a fan of dirtbike/supermoto's and the multi feels like a giant supermoto and is incredible fun for something with only 85bhp. Its also far better than the st4s in traffic and as a town bike, the upright riding position being good and the low down torque is great for town and back road hooning.
Having said that its still the 996 that's taking me to France and Spain next month for a good thrashing, but its the Multi thats going to Morocco later on in the year.Horses for courses, depends on what you want the bike for.
The power difference is big, the Multi at the risk of being abused by other Multi riders feels very user friendly and 'Honda' like in comparison to the 4 valvers. I'm sure Honda could produce a version someway between the firestorm and varadero.
The Multi is a very deceptive bike but a good laugh, don't just look at the power figures, you've got to ride one, i didn't intend buying one when i test rode it.
Handling wise, its very easy, relaxed and surprisingly good, just lob it on its side and let the torque whiz you out, its so easy with those big bars, doesn't even feel like its working hard, again just like a big supermoto
