Thanks and I guess I would have to find a video on that gear change.

2.91 still is a big change from stock. Next time your in the mountains take a video and I will make some more popcorn! LOL

I guess the final question is are you happy with the 2.91's?

Thanks Again

Later Steve

I think the 3.20 gears might just as weak as the 3.36 gears. I have a 2.91 gear ratio in it right now & those gears are the same size as the LT gears. My different final drive gear ratios that I have are complete & I just put them in a box still filled with gear oil until I'm ready to use them again. It's less than 30 minutes to swap them out.

Thanks Saddleman:

It sounds like you change out your rear drive depending on trip specifics? Personally I am not set up in my garage to get into those kind of "Spontaneous" changes. If I make a change it will be permanent. Weaker gears doesn't sound too good considering how we all have to worry about rear drive failures anyway. I am in Seattle and limped home from Norcal with a impending drive failure. I was very lucky. 1- I made it home, 2- I was out of warranty but Ridewest covered it anyway!!!. The 3.20 gears might be the way to go me thinks!

Thanks again for your help :-)

The 3.36 gears are for a R850R and the length of each tooth is shorter and weaker than the LT gears.

I have been to 115 mph on the gps in 5th gear and it wasn't at red line yet.

The ring & pinion gear set cost $660 from BMW Germany.

I will keep this final drive on the self unless I'm riding in the mountains. I think a 3.20 gear from a R850RT would be better because I was shifting to often with the 3.36 gear.

Hey Saddleman:

I have been riding my 99 LT like that for 13+ years. Not all the time though but when I do the temps do get almost to the caution area. Note that I have the Chip / Exhaust mod. Actually the noise is starting to get to me but I am a lot older now LOL.

The ratio change looks interesting. Can you provide more details like, 1- Are the gears more reliable (You know what I mean!) 2- What is your top speed now, On long trips out west I cruise at 90 all the time and I think that is about at 5000 rpm but will have to go check that out again, What is your rpm @90 :-) 3- How much did you spend on parts and where were they purchased. 4- Any other special items of interest we should know about this change?

Also after riding on the 3.36 for a while would you consider a different ratio somewhere between the stock and 3.36?
Thanks Steve A

BMW K1200LT w/3.36 final drive - mountain ride - YouTube Look at the temp gauge it was in the 50's F and I couldn't ride like this in the heat of the summer. I'll need to get more air through the radiators. The video always looks slow so the dash cam gives you an idea of the speed.

And why not? At this RPM level, the LT will make Fun Bobby much more fun, esp when riding with Harleys!

David it was just a shutter effect on the GoPro that made the Clearwater Lights "look" like they were flashing. The eye cannot see that.

Federal law allows for "modulating" white lights on the front of motorcycles for safety. Some companies have pushed this a bit with the flashing LEDs. I have some that were marketed as "modulating", but they definitely flash, so I haven't mounted them. I want to hear from a Judge that they would be allowed first.---------------------------.

...I also don't turn 7000 on the RPMs either

Saddleman, one of my Harley riding partners was watching your video and asked if your exhaust was stock? He said my LT didn't sound like yours. I also don't turn 7000 on the RPMs either.

Nicely done Dave. Perhaps a switch and an isolator diode for the fans would help with the air issue. I bet your tires never get changed because of being thin in the middle, huh?

Wow! Iv'e had my bike for 12 years it hasn't been over 4k rpm in all that time, nice job

Neat!
Thanks for posting.

Is that a K1600GT(L) with the flashers trying to keep up with you?

That looks pretty quick, particularly from 60-80mph acceleration. Seems to me that a milder ratio might be a nice compromise.

Now your friend's flashing front lights might get him in a bit if trouble - I initially thought it was a LEO that you were running from....
