The NF5 won't fit the NSR swingarm linkages as it uses a 'fork' type mount at the bottom, not an 'eye' type like the NSR.
A better bet is to fit an old CBR600 shock or an RS125shock as this is the right length and fittings. The big problem with the RS125 shock is the standard sub frame needs cutting to accomodate the reservoir.
Check out Si's MC21, he's had one fitted.
Good luck!!

Anyone know if that length would suit the mc21?
