Default Improving handling on 2010/2011 models?

So I've heard the 2012 is more agile than the 2010/2011. What can you do to improve the handling of the 2010/2011 model so that it turns in as well as the 2012/HP4?

Better suspension will get you on the way. Full set of Ohlins on a pre 2012 will probably out handle a later model. Actual turn in maybe a bit more of a chalenge since the distance between axles has been slightly reduced.

There is a 2012 front end on ebay right now for a super low price. That front end plus the swing arm pivot offset from a reputable vendor might get you close, assuming all the other changes play nicely together.

Per BMW the 12's had "Suspension geometry modified with new values for the steering head angle, offset, position of the swing arm pivot, fork projection, and spring strut length."

Alpha Racing adjustable offset triple clamps would probably give you all the adjustment you need.

I think doing the swingarm offsets and a triple clamp will get you most of the way there (having owned both a '10 and a '12).

Dave Moss has developed a formula for certain spring # and other specs for the front suspension internals that will make the bike turn and handle much better. Contact him for the exact spec and story

Triple clamps made a big difference to mine, I'm running 28mm triples, +3.5 swingarm pivots, ttx rear shortend on the adjustable bottom yoke, 30mm cartridge kit. Very sweet and better than a stock 2012 having ridden both.

I put Attack Performance Triple clamps w/#4 off set. I tweaked a lot of other parts, too, but the triple clamps made the steering quicker, easier, and more fluid. These are racer triple clamps and make no provision for the ignition. I've heard that some other brands do. Bottom line is change the rake and trail from 30mm to 26mm.

Are the 2012 chassis changes only in the triple and swingarm pivot points or were there changes in the frame.

These numbers/data are from the press release

"The new S 1000 RR features a modified frame with a new steering head and tail section. Besides new key figures for the geometry there is also a 20% larger cross section of the intake air guide in the steering head. The steering head angle is now 66° instead of the earlier 66.1°. The wheelbase has now been shortened by 9.3 mm to 1422.7 mm, and the afterrun has been lengthened by 2.6 mm to 98.5 mm. The fork bridge offset (front end) is now 2.5 mm shorter at 29.5 mm. In addition, the fork projection is 5 mm shorter than in the predecessor model. These modifications also included revisions to the steering head bearing for a lower breakaway torque and hence greater steering precision"
