You're clearly used to the bull***** that the Japanese manufacturers put out there. I had to educate a co-worker of mine that his '00 CBR600f4 didn't actually weigh 374 pounds dry (407 actual)and it didn't actually make 110 hp (95 actual) Ducati, unlike the Japanese manufacturers, has long quoted rwhp and is rarely off by much. I think the whole industry is finally coming around to this, but the big 4 Japanese companies have been pretty bad in the past.
The first (2003) Multistradas were quoted by Ducati to put out 84 hp and most dyno tests show 81-83. MO got 81.95 hp during its 2003 Funky Twins shootout. The engine was claimed to put out 92 hp for the SS version and I believe all models (Monster and Multi)were given SS spec engines for 06. Dyno tests for the SS spec engine have been about 88-89 hp. My guess is the 1100 DS engine will show 90-92 hp on an dyno. Perhaps what you need to understand more than that is the 76 lb-ft of torque and the fact that all hp and lb-ft are not created equal. HP and torque curves matter. The 1000DS is a very entertaining engine and the 1100 will likely be even more so.
Test ride one of these bikes and let me know if you still "need" more hp.
Maybe you will. Maybe you're an adrenaline junky and just like the rush of arm-pulling acceleration. That's cool if you do. Maybe you're one of those guys who simply must be able to spin up his rear tire at any time and/or do stand up wheelies on the freeway. If so, then you "need" 150 hp so go look at a GSX-R 1000 or ZX-14 etc. If you like to really like high rpms and like winding a bike up, grab a newer 600. Different strokes, blah, blah, buy what you like.
