Has anyone ever tried to put a 6sp transmission from a V11 into a Centauro or Daytona? Ed Milich is selling a low-mileage trans, and I'm tempted to try the swap.
-
From a ratio standpoint, the 6 speed has only about 8% more spread, 1st to 6th than the 5 speed, with low being 5% lower and high being 3% higher. From my point of view, the main difference would be having to shift more often, so I'd stick with the 5 speed. Your preference may be different. :)

Yes.

Clearly it will mate up, and I'm guessing that it shouldn't be too much of a problem getting it to work.

Yes. Greg King did it, when he was living part time in Charlotte County, VA and part time in The Philippines, and we were riding Centauros together.
I don't know if he monitors this list any more; I haven't seen him in some time and he may be permanently overseas now, retired.
He did a beautiful job on it - if you didn't know the bikes real well, you'd never know there had been a change.
He really liked the 6-speeds; me personal, with all the torque that bike had, 5 was plenty for me.
By his way of it, it wasn't a huge job to change over - an adapter plate and minimal machining, but then again he's an excellent mechanic and what might sound easy to him would be hard for me ....

Paul Mineart has a six speed Daytona. It was a lot of work.
-
I'm interested in the swap because shifting the 5sp in the Centauro I had years ago was a clunk fest. The shifting quality of the 6sp is vastly better. Pete - do you know what was involved in Paul's swap?

It's not that hard if you keep on the recipe. It has been done a lot of times. After I showed how it goes. I did this in 2003.

Yeah. :smiley: All I get is "How to V11 gearbox"

I choose to move the swingarm pivot 60mm to the front, but that is more complicated then in above link.
That you can find here:

The 6 speed box is lightyears better shifting the any 5 speed box. Even much better then the Carc 6 speeders.

Yes, given the right mechanic / time / tools, you could install a 6-speed, but why? :rolleyes: :shocked:
Leave it stock, and 5 speeds is just fine...(IMHO) :thumb: :cool: :1:

Difference in shifting quality between the 6sp and 5sp is like night and day. Also - I have a machine shop, and there's not much riding in Colorado in the winter. So - why not? Winters can be long here ...

OK - On the open highway, I admit, I have enjoyed 6-speed gear boxes on my former 2011 Triumph Sprint GT and my current 2014 Victory Vision...so wrench away :1: :thumb: :cool:

God the're gorgeous... 'Can't think of a better looking bike in a raw sense, better than a Panigale or similar.
-
Although come to think of it, a swingarm styled like an Aprilia RSV or similar would complete the look.

Yes, shifting is light years better with the 6 speed, but I really like the long pull on the RS. And it's really a 4 speed as I rarely put it in top gear unless I'm riding on the freeway.

OK, How about the V11 6sp in a Tonti LeMans? This is what I'm looking at right now, instead of changing all the dogs @ 50Kmi in my 5sp.

That would be an interesting project and I can hardly wait for the step by step photo's. :smiley:
Personally, I wouldn't mind the six speed with the entire rear swing arm assembly,etc from the MGS-01.

Hold my beer while I get my welder & grinder out.
1st I have to get a 6sp box.
Can't believe no ones done it.
-
Problem is Steve the gearbox output shaft is too far to the right. I don't think it will fit in a Tonti.

Is the final drive ratio the same for Centauro's and Daytona's? Plus, acceleration times will be longer if a gear change is needed. R3~
-
I have never seen a drawing of the drive lines and the spacing in anything or books anywhere, just know the motor was jacked way over to one side w/V11S. I know it's bout 2" shorter.

FD ratios are very different I believe. Thing is AFAIK nobody has ever done it. Given that the V11 series is now near as dammit 20 years old you'd think if it was easy, or even possible, someone would of done it by now.

no they are far apart. The gearbox shaft is not only more right but also down. So having the shaft in the are is a no go. Only with a open shaft you have any chance. I suppose putting the v11 box/swingarm/ reardrive in a tonti would be the most easy. "Only" the right pivot would need to move right. Width at pivot is the same with daytona and v11. The swingarm is 400mm long.

I've now acquired the V11 transmission, driveshaft, and swing arm. I already had a rear drive. So - a question for Paul - would I be better off using a V11 front subframe, or will I still need to modify the stock Centauro subframe to move the motor to the left?

More easy to use the first series v11sport front subframe, that fits without work. The second and later series have extra tubes that are in the way. The first look like the centauro one, but have also the bonus of the oil cooler mounts.

I can't say that I really like a 6-speed gearbox in a big twin but that is where marketing has drawn many manufacturers, even Harley Davidson.
I like the longer pull between gears with a 5-speed that allows you to feel the torque curve of the motor. The 6-speed chops the power curve up too much for me. It's shift, brief throttle, shift again.
My former Daytona RS (now in the hands of Blackcat) was not clunky in my opinion. I had shortened the shift lever throw and it worked fine for me. I rarely made 5th gear on that one. 3 and 4 were better for most riding.
The same is true for my H-D. On my recent Blue Ridge trip I rarely had it out of 3rd. In 3rd, it pulls very quickly from 35 mph to well over a 100 before redline.
Heck, I really liked the 4-speed in my '67 V700. It too was not clunky. The 4 gears gave plenty of advantage for that motor. Ditto for my '78 H-D 4-speed.
Yes, the 6-speed transmission on my Scura was the best shifting transmission of any bike I've owned. I think that fabulous aluminum flywheel and single plate clutch was responsible for a lot of that. However, I still really like 5 speeds and sometimes maybe even 4.
To each his own.

That's the thing about a manual shift transmission. You can pick and choose which gear to use and when to use it.
If the speed limit is 45mph, why wade through 5/6 gears. Wind it up in 1st and shift to whatever gear you're going to use to cruise.
-
Ha - and some people want to put a Centauro motor in a V11. What a bunch of crazy gearheads (takes one to know one). :popcorn:
-
I've owned a Sport 1100 (carb) 5-speed and a V11 LeMans 6-speed.
For me, the lower 1st gear of the V11's 6-speed was welcomed when riding in town or in stop and go traffic.
The 5-speed's shifting in the carb Sport is agricultural compared to the V11 LeMans' 6-speed, but that does have its charms.
Running twisty two-lanes, there isn't much difference in the shifting needs. Basically use 3rd and 4th on Sport 1100 in the same places I use 4th and 5th on the V11 LeMans. Both bikes' torque curves don't require a lot of shifting unless the going gets tight.
So, for me, the two biggies for the 6-speed are the lower 1st that helps in traffic and with a passenger, and the smoother/easier/quieter shifting.
