Had a 21 s1krr sold it at 13.5k, now have a 24 m1krr. I love the differences. As noted earlier, the ride position - I did put different clipons on both. Gilles GP-2. They went down apox 1cm, below the upper triple, forward 2.5cm. Feels dirt bike-ish. Much more comfy for a big guy like me. I have the SE moto tank cover too. Squares off the tank, better knee purchase, more surface to lean into when hard braking. I love the riding position now. Rear sets are perfect in my opinion. The seat is awesome, just don't expect to sit for a long time. The M1krr stock riding position was too relaxed for me.
Totally agree revs faster. - I tweaked that too.. I went down a tooth in the front. now 16 tooth, thank you HHRPerformance. At first I went down 2 teeth, and that was insane. For me down 1 is perfect.
Bike doesn't burn oil, doing just fine, 1900 miles BT stage 2.
Sounds sexier with the full exhaust.
Brake feel is better, but I attribute that to the 'M' brake pads. The master cylinder feels the same, not wooden.
Suspension is soft for me, so I changed the spring rate. I'm 250# w/o leathers.
EDIT: OOOH the QS stock was great! But I cant leave the bike alone, so it got the Alpha QS.
Thinking about more convenient chain adjusters now....
Love the change to the windscreen too, actually a lot.
