Allo,
I had my 748 turned into a 853. Neil at Sigma completed the work. The 853 pistons weigh the same as standard 748 ones so no need to re balance the bottom end. My bike still revs to 11500 and makes the same power as a 916. So best of both worlds
Its a hoot to ride too!!!
Hits 160 no problem. On private roads of course!!
I thought that if the 916 pistons were fitted then the crank cases would have to be opened out??
