Throttlemeister installation on a Yamaha Fazer

Since my sportbike is being set-up as a sport-touring mount, I thought it was time to install a nice throttle lock. I never had one in the past, and always regretted not getting a nice unit. Riding for long distances on the highway can be very fatiguing on your hand/wrist, and a throttle lock is a nice way to hold your speed steady. Plus, they are all fairly simple to install. I had no intention to go crazy and use an available electronic cruise control, so the bolt-on lock was my choice.

There are several very inexpensive units on the market that will lock your grip into place, and though they get the job done they do look rather cumbersome. However, several of my friends use the Throttlemeister system for distance riding. I always liked the very clean look - they appear to be just shiny bar-end weights - and the users have raved about the fit, finish and quality of them. I wanted a great unit, so I placed the order for one to use on my Fazer.


Here's the instructions, and I love some of the warnings they printed. Hooray for personal injury lawyers!!

The unit arrived a short time later. At a little over $115.00 to my door, it is not a cheap unit. However, upon opening the box you can see why it costs so much more than your typical $15.00 plastic set-up. The Throttlemeister is a machined piece of aluminum, brass and steel that comes with two units - matching bar ends. One side is the lock, and the other is just a bar weight to lend symmetry to the bikes visuals. The product just screams quality. The polishing and machining are perfect, and the fit and finish of everything was spot on. The other surprise was the directions! There was a sheet inside the box with a detailed but simple explanation on how to install the unit. Givi could learn something from this company.

After emptying the box of all the parts and making sure it was all there, I took a look at the locking mechanism and tried to figure out how it worked. It was fairly simple, and worked by rotating. To lock the unit, you would roll it towards you, like when you accelerate. To unlock, just roll it away from you. The action was very smooth and everything worked. One other thing I noticed was that the bar ends were a bit heavier than the stockers on my Fazer. These new ends would do a nice job of helping to quell the little vibration I do get through the grips from the engine.


Here's what comes in the box, the unit's pieces laid out, and look at the quality of the machining. Very nice.

The obvious place to start was with the removal of the stock bar end weights. The removal of them was fairly simple with an Allen head socket. No fighting, they came right off. Next up on the throttle side was to install a special adapter. This piece fits under the rubber grip, but over the throttle tube. It will then stick out slightly over the end on the throttle, allowing the actual Throttlemeister to lock to it. The adapter will be locking the throttle tube into place, and the metal Throttlemeister will not be rubbing the grip.


Removal of the factory bar-end weights, and installation of the adapter sleeve.

Next up was to mount the Throttlemeister unit. This just bolted right up in place of the factory bar-end weight. The only difference now was the inclusion of washers in the kit. These washers will help create space between the metal friction plate and the plastic adapter sleeve. More washers = more space between the two. I started out with all three washers, but ended up using none. The Throttlemeister unit would lock up perfect, and yet not rub against the grip when not in use. The throttle would still snap back nice and smooth.



Comparing the old and new, mounting the shaft, all the parts, both units, locking the shaft in the bar and tightening it up.

Even though the instructions called for the use of a thread locking agent, I didn't use one. I was thinking about if I had to remove them for any reason - such as changing grips - that I could damage the Throttlemeister trying to remove it. Since the shaft itself doesn't spin, a properly tightened unit shouldn't just fall off. I then installed the left-hand side unit and since this is just a bar-end weight and nothing else, it went on in about one minute. Very easy.


The first photo on the left shows the throttle in the normal position, and the second photo is the locked position. The brass colored inner sleeve rotates out to apply pressure to the plastic adapter unit. And finally, the finished product on the bike. It looks great!

Though I haven't ridden the bike with this unit installed - it was snowing and 20 degrees out when I did this - I have no doubts that it will work just fine. Though pricey, this set-up is first class and looks fantastic. Unless you plan to go with an electronic cruise control, this is by far the next best thing.
