hey guys, my older brother has a 1998 R1100RT and I'd like to get him a cruise control for the bike for christmas. I can't find the handlebar diameter online anywhere. should I be after a 1in of 7/8in diameter unit?

thanks in advance

Allow me to suggest you get him something else. My BMW mechanics tell me those things never really work right.

i have the eltric cruise control on my gs 800 (it came with it) don't waste your time with it. when i ride with other riders i cant use it because everyone else hase throtle locks and they speed up and slow down with the hills and terain. mine stays right where i put it. this is great but no one else will drop the money on them so i am constanly adjusting it every dand secound it feels like. i just give up and use the throtle lock like everyone else and then keep up with the pack.

now when i do love it is when im out by my self and just want to set and forget., but the trottle lock will do the same thing for a lot less money, put the money into better horn, deinally lights or better yet a riding course (you wont belive what you will come home with in knoledge from them)

just my 2 cents on them as i have both and hardly use the thing. i know my next bike won't have it

I don't have that particular model of BMW but I have owned a BMW bike.  Try googling R1100RT Throttle lock instead of cruise control

Kaoko

Throttlemeister

Here you go...

My K1200LT has factory electronic cruise and it works flawlessly.
It may be available for the RT  but it will be spendy.

'74 R90S.

No cruise control for me.

the reason I ask if I wanna pick up one of the go cruise "throttle clips" but they make one in 1in and one in 7/8in just not sure which one to get. for his bike.
if you haven't seen em before, check em out, simple effective, low cost solution. they make a great stocking stuffer at christmas, I've given em to most of my friends the past few years

so whats the verdict lol, 1in or 7/8 in?

I'm using this o-ring and it holds the throttle really well. I had a Wunderlich installed but it didn't work correctly.

R75/5, no cruise. Not much of anything else either.

I am 99% sure it is 7/8ths

BUT I would skip the cruise and go with either Throttlemeister or Krakoa (however the fuck it is spelled) UNLESS, you want to spend a few hundred or more on fully electronic

I don't know for sure, but back in the day when I had foreign bikes they were all 7/8 and Harley was 1in. But the foreign bikes were Honda, Suzuki and Triumph for me and that has been some years ago.

I think the throttle lock is a decent idea for long tours and strait flat highways, I put them on a couple bikes that I rode any distance on.

I'm if I'm gonna be on the bike more than an hour I'll throw a go cruise throttle lock on the bike. yeah, i'm lazy as dirt

I have a Throttlemeister on my VFR. Works well but pretty expensive for what it is and does I think.
It's unobtrusive though,just looks like a silver bar-end and is easy to roll on.

7/8"

 

Mine is 1", FWIW. Go with that, IMO.
