Install a 6-speed trans on a 2013?

As noted above unless you are racking up lots of highway miles having that 6th gear is not really a factor.

Max tq on this bike is at 5000 rpm so steady cruise at 4000 rpm or so keeps you right under the tq peak which means downshifting is not required in the event you need to quickly accelerate. I’d advise against running around town at 2500 rpm in 6th. If you get in a tight spot and need to accelerate quickly you are gonna need a downshift. Just because the bike will run 6th down low like that does not mean it’s ideal.

All my riding is city in the Dallas metroplex, many times I’ve had to quickly roll on the throttle to avoid distracted drivers. Regardless of speed if the revs fall below 3500 I’m looking for a lower gear.

A lot of bikes won’t tolerate lugging, my Monster 1100 was a 3 speed unless you were doing 50+ Mph

This bike isn’t ..that…

These bikes- even stock will run at 2500 all day long.

There is no such thing as lugging a modern CB 1100 unless you are a complete bonehead.

Any machine can be lugged, technically if you cannot quickly accelerate away in gear you are lugging the motor. The CB does not protest as it’s in a very mild state of tune.

What happens when you quickly open the throttle from 2500rpm in 6th gear? Nothing as you have the acceleration capability of a Nissan Sentra for the first few seconds until the motor spools up.

Now do that again in 4th at 4000 rpm…huge difference in response

"I would however trade any pre17 for one of the rare EX. Simply the more fine-tuned model."


Only true improvement in my mind is the front forks, while the gas tank looks goofy. And has a slipper clutch if you care about such things... I own a bike with one and haven't noticed a benefit.

You only notice the benefit of a slipper clutch if you downshift too early like an inexperienced rider. Those who have the natural feel and mechanical sympathy for their bike, which comes from experience, shouldn't notice the benefit.

So slipper clutches are for inexperienced riders….now I’ve heard it all.

Slipper clutches are designed to release clutch back pressure when doing high rpm downshifts, this prevents the back wheel from locking up. Why do you think every ultra high performing machine today has one?

I realize this is a grandpa bike and most are ridden as such but regardless that’s just a silly uninformed statement
Bottom line is if you ride the bike hard enough you will notice the benefits
