Have a look at any post in the last couple of years either on here or Boxertrix and compare those to 10 years ago or even 5 for that matter everything now comes down to money as for the sprockets themselves,if you have a 1200 don't go fitting them and then try to have a Rexxer map blown in because they won't do it,doesn't take any working out does it.
I've had my 1100s close on 14 years from Dymags to Ti front wheel spindle and god knows what else in between and it's still on going more torque?? out of an 1100cc twin
,quicker steering,less weight, more HP and quicker and I'm more than happy to put my induct/SJ filter/PC with a custom map anything else,the one thing I know about torque it lets you laugh first,HP lets you laugh last!!
