The gearing can be raised by changing rear tire sizes.
At the same revs a 140/90/15 gives 4.6% more speed and a 150/90/15 (if it fits) gives 7.6% more speed.

I understand 'Za', if you ever rode a 6 speed, your foot keeps wishing for 6th. I rode an RD parts bike before I put the front end on my Kawy. Ruined for life!
Even if the Suzy's 5 speed gearbox was spred out w/ wider ratios (like the 1st generation LS's,and making 5th higher) I would always want 'one more' now.
My thumb wishes the blinkers were self-canceling like some of my compadres Yamaha's too.
My Savage's turn signal center cancel button is mushy.
I will press it and sometimes the signals fail to cancel, not good, just begging some cager to pull-out.
In the daylight the edge of my sheild hides the too-dim turn signal indicator. Midday I can barely see the indicator unless I look down. I am considering adding a small beeper to back up the indicators for noon time riding.

All I know about chain drive is that the LS400 is chain driven.

I ride them and fix them.  Sorry MR650 if you don't get it.  Your ignorance and intolerance are your problem.

A 600 katana front sprocket is supposed to fit.
