for those who are unaware as I was, crampbuster comes in at least three models. a wide shorter model; a longer narrower model with a smaller diameter handlebar curve; the same model with a larger diameter curve. these are held in place with 'spring' tension built into the plastic. a fourth model uses a velcro strap, I don't know who makes it. I have used both 1 and 2 and I like the second one best for my 650.

Likewise...I have a ThrottleRocker....I leave mine
adjusted for my normal 60ish MPH cruise to work.
Also have the Cat-O-ring cruise-control...leave it
in place all the time. I'm a bit spoiled now. :D

Like duster, I have the Throttle Rocker and Cat-O-Ring cruise control. But I had to remove the Throttle Rocker when I installed the Grip Puppies. I find that i miss it on longish rides though the "cheap cruise control" helps in that department.

I forgot to mention, I roll the crampbuster around so the lever part points down and out of the way when on short trips or around town. I tried the velcro one but it wouldn' t budge(roll around out of the way). The type I use only 'grips' in one direction. to each his/her own :)

I bought the regular sized crampbuster for my 400, and found it too long, it kept catching on my jacket sleeve, so I cut it down to size, just to the top of the Crampbuster logo, and now it works fine. It still rests on the palm of my hand comfortably, but doesn't get in the way, plus its easier to roll it out of the way when I don't need it.

Some people have gone the cheap route for a sort of cruise control. The caterpiller O-ring sits in the gap between the bar end weight and the throttle grip. There is enough friction to hold the throttle in position until you need to change it.

OK, so I just installed a Crampbuster as my first mod! Seemed to be a big help on my 20 mile ride to work down a highway...and it is easy to move out of the way when I'm not using it - BUT - what do you guys do when traveling at slower speeds once it is adjusted to when you want it? It's in the very middle of when I normally grip during these periods and it almost feels unsafe. Can any of you adjust it while moving? I only have 2 hands and I haven't figured out how to adjust while going down the road... :wink: Any adjust while in use requires the throttle goes back to zero, doesn't it?

I am a noob, so any rolling of your eyes only hurts my ego, not my feelings! :cheers:

I had the Crampbuster, but ONE time because the Crampbuster position ... it interfered with a quick stop.
I grabbed the brake, but the throttle was still open because of the position.
I removed the Crampbuster immediately and replaced with "Wrist Rest"

The "Wrist Rest" which has the ability to pivot moving the position as needed, does not interfere with quick/emergency movements
plus it provided more usable hand positions.

I use a Throttle Rocker, positioned on the Right side of the grip as shown. Uses just the heal of your hand, not the palm.

I have had mine over 4 years, and never take it off.

I stopped at a bike shop to pick up a Crampbuster; I asked for it by name & they looked at me like I was crazy. When I described it, they said, " Oh, a Throttle Rocker, here!", so I bought it.

It's pretty handy, though I see now that I would prefer to have the ability to easily swing it out of the way. Well, for $10, I can still order a Crampbuster & compare them...

Hi Goldberg, I keep my Crampbuster on the extreme right side of the thottle so that I use the right side of my palm on it. I leave it in one position and never have a problem, though I cut mine down to size so that it was not catching on my sleeve.

I just got a Throttle Rocker. Will take some getting used to. For highway speed cruising position, the paddle of the device is angled up at about the 10 o'clock position at idle. That means I have to kinda sorta arch my wrist awkwardly when doing lots of in-town stop-n-go. Have already had one quick stop (RV in front slammed on the brakes in front of me, but his brake lights weren't working...took me a couple of seconds to recognize and react) and found the TR interfered...I was revving the engine while braking hard.

For now, I'm taking it off for short rides and putting it on for longer rides. I will say it certainly allows me to relax my hand and shoulder while cruising.

That is exactly why I replaced the Crampbuster with the Wrist Rest.
The Wrist Rest without throttle rests at the 8-9 o'clock position (6 being the ground - 12 being straight up) .
When you have to brake quickly your passes over the grip, which the Wrist Rest does not interfere with.

The Wrist Rest allows or a full 180 degree pivot allow even more comfort positions by moving the pivot with your thumb ... though I only moved it on extended rides.

I googled 8M4991 and got no results - how do you find the correst O-Ring, or what is the correct size for the 400??
 
#19 ·
8M-4991 is a Caterpillar part number. I buy the o-rings from a local Cat distributor and they are dear: 7$ a piece. Someone posted that they get theirs from an auto-parts store for a few cents..... not $$$$. But the Cat O-ring has a nice color, is a conversation started when people eventually ask what the "yellow thing" is for, and it retains its elasticity throughout the season. Mind you, I remove it when I put the Alfie away for 6 months being in the Great White North.

I'd venture that the same size would fit both the 400 and the 650 but that is just an assumption.
 
#20 ·
For the 400 I used cat part number : 8M-5266 The specs are :

  • cross section diameter 5.330mm[/*:m:3rflkgic]
  • seal inside diameter 24.770mm[/*:m:3rflkgic]
  • dash size 318[/*:m:3rflkgic]

I cheated...I just dug around in a cardboard box full of O-rings
in the heavy-equipment repair shop at work.
Guestimated on the size....stuck several on my fingers...
shop supv. told me to stuff them in my pocket & vamouse...
come back another time if I needed any more.
I limited my choices to rings that were not in any packaging...
all loose stuff in the bottom of the box.
I've already passed out most of them to other riders.
