Can i install mono suspension to my boxer and if, how?

Having Mono suspension in a boxer is not really a good idea.
There is no right area in boxer to give proper foundation for the mono suspension, ultimately you will end up screwing your bike.
I say No to Mono suspension in Bajaj Boxer.

my actual plan is to experiment.

yes its ur bike do whatever u want but try only if you are expert or used to such things

so what are your plans ?
I guess Mono shock is just part of those plans .. right ?
