CB160 and CB175K0 Gear Ratios

Here's one for the experts. Whilst they seem outwardly the same, it appears that the CB125K0 and CB160 have four gears and the CB175K0 has five.
Is it possible to do a swap or are there major differences? I don't have access to a CB175 but it sounds like it would be nice to get a 175 gear cluster for my CB160.

5 SPEED GEAR SETS REQUIRE THREE SHIFT FORKS. FOUR SPEED GEAR BOXES HAVE ONLY TWO SHIFT FORKS.

Thanks for the info. Is it possible to swap the shift drum and forks etc? I know it would make more sense just to swap the whole engine but I was just curious.

Wow! Great link! A bit like the Bantam racing club in the UK only with nicer sounding bikes.
Many thanks

Thanks for your help. The notes on this page suggest that the swap is quite straightforward.

I have bought a complete CB175 5-speed transmission so that I can try this out. I'll post the results here.

The last one I fitted wasn't too difficult but required a small amount of welding and machining for the bearing on the shift drum. The gear shafts drop straight in as I recall.
