The CB1100 Community Forum

My math works out to be about 2 1/2 percent lower gearing 1-5 on the 14. I doubt you will ever be able to tell the difference. Lets say the 13 runs 4000 @ 70 in 5th the the 14 will run 4100. Nobody will ever notice the difference imo. The ever so slightly lower gearing should over come the little bit of extra weight when accelerating. Again, its so small that I doubt anybody will notice but we will find out soon enough.

I selected the 1983 CB1100F in the gearingcommander.com and then changed the sprockets to 18/39. That gave speed at 4000 rpm as 70.5 mph which is very close to our CB1100's.

then if you enter a custom rear sprocket of 40, the new rpm at 70.5 mph is 4102. or the change in speed at 4000 rpm goes from 70.5 to 68.7 mph.

if we knew the 6th gear ratios we could enter it in manually and the program would give a very close estimate to what the 6th gear will do.

Can't believe Honda hasn't released a brochure or anything anywhere on the web with the 6th gear ratio by now.
I rented a BMW R1150R once and that was a real overdrive--I'm doing 75 with the rest of San Diego traffic with the engine ticking along barely awake at a little over 3000rpm.

One of the least intelligent metrics US motorcycle magazines focus on is the top-gear roll-on. The mfr's think that's what we all want, but I want a real overdrive. Downshifting to 5th (or 4th) for a little extra squirt when needed ain't that much trouble.

And if the CB edges out the Bonneville, I'll most likely be changing the rear sprock back to a 39. (Heck, OldF7's right; one tooth on the rear ain't even enough to notice, maybe even a 38. If the ol girl's speed sensor is located at the drive shaft, that might even be enough to trick it into 120mph.)

Hey, Chris, where are you up to with buying a CB1100?

Hey, Cormanus, thus far it's either CB11 or Bonneville T100 with a few mods. So far we're leaning pretty heavily toward the prettier Bonneville, but an honest OVERdrive might be enough to lure me. (But both Triumph and Big-H are lucky that Kawasaki ain't bringing the W800 to my puny, small-minded Isle, because it's a superior bike in every respect.)

I looked hard at the W800 just before I bought the CB1100, but I just couldn't shake my fixation on having an inline 4 just once in my life. It's passion not logic that drives us in these things. The dude who cuts my hair (who, like you is a mad-keen peddler) has just bought a W600. I've not had a chance to look at it yet, but I'm looking forward to it.

The Bonny is sure a good looking bike ...



As to puny, small-minded islands ... well, that's not a matter for this forum!

Some of us are passionate about logic, doctor.



(That is a very pretty pic of that Bonnie, but I ain't much into that asphalt-camouflage colour.)

Found this info on the 5 speed still looking for 6 speed info

Transmission 5 speed
Transmission gear ratio
1-speed 3.166(38/12)
2-speed 2.062(33/16)
3-speed 1.545(34/22)
4-speed 1.250(25/20)
5-speed (30/29)
Final Drive Chain 2.166 (39/18)

The following is translated from the Honda Japan website.

1 speed: 3.083
2-speed: 1.941
3-speed: 1.478
4-speed: 1.240
5-speed: 1.074
6-speed: 0.964
Reduction ratio (primary/secondary): 1.652/2.222

Ok thanks to Guth we have the ratios, now one of you smart guys ( not me) can figure out exactly how much difference the additional gear makes.
