This is a simple but effective cruise control solution. On long rides, the throttle hand can become tired and cramped. With the Throttle Lock installed this becomes less of a problem. The Throttle Lock simply replaces the right hand side bar-end weight, and by turning the adjustment wheel, the Throttle Lock applies pressure onto the end of twist grip and the force of the throttle return spring is reduced or eliminated.

The adjustment wheel has wide spaced teeth that allow easy turning of it even while wearing a glove, so it can be dialed in to exactly the required pressure. To disable, the adjustment wheel is simply turned in the other direction and in a matter of seconds the twist grip returns to normal function. For safety reasons, our throttle lock is designed such that tension is applied by turning the adjustment wheel in the opposite direction of throttle action. In this way, tension can only be intentionally applied.

We offer the Throttle Lock in your choice of black or silver. Both versions have a blue adjustment wheel. On both versions, the entire assembly is made of anodized aluminum and a matching left side weight is included. Being made of aluminum, these bar end weights are lighter than the original steel parts. Installation requires a T55 Torx wrench or socket and takes only seconds to carry out.

Installation Hint 1: Our throttle lock and matching left weight are slightly shorter than the original bar end weight on some models. This in itself is not a problem however, the bar end weight bolt is installed with thread locking fluid at the factory and in some cases, there’s an excess amount of hardened thread lock on the inside of the handlebar. Because in some cases the bolt needs to be screwed in further than it originally was, you may feel that the bolt is bottoming out. In this case, we suggest that you use a tap to break up the thread lock and clean the threads. You’ll then be able to fully screw the bolt in and tighten it. It is a good idea to apply fresh thread locking fluid on the bolts to ensure that the bar end weight bolts do not accidently loosen.

Installation Hint 2: For optimal operation, it may be necessary to adjust the position of the throttle sleeve in order to achieve the proper end gap. Watch the video for information about this procedure.

Tip: We also offer blue anodized bolts to replace the original T55 bolts. The blue anodized finish adds yet another stylish accent and compliments the adjustment wheel of the Throttle Lock. You will find these bolts under the Related Products tab.

Throttle Lock did exactly as promised

Reviewed by Bruce Kennedy from Barryton, Michigan (9.29.2015)

Just had my 1200 for a month and needed a good throttle lock to releive my right hand. It installed in about 15 minutes and has worked as expected and finish is first rate. I do have a little trouble activating with my finger to the extent it holds but it still allows me to then adjust a little tighter with a couple fingers. I like that I can make little speed adjustments for a hill or a downhill and relax.

Easy to insall, difficult and dangerous to use

Reviewed by Nuuguy from Clute, TX (8.30.2015)

The operation is backwards and jacking with it trying to set it while riding is dangerous. Threw it away. Bought a Kaoko. This is the only Wunderlich product I have not given 5 stars.

Throttle Lock for BMW F540

Reviewed by Carl Crowe from Bentonvile, AR (4.27.2014)

Installation was only about 5 minutes. Precise easy fit. I mostly use the throttle lock to reduce the tension on the throttle. It works great and since the threads are close together it's easy to find the sweet spot you need.

Surprisingly bad

Reviewed by Spike DeClue from Albany, CA (4.5.2013)

After just a few weeks of regular riding, the aluminum was being worn down by my gloves. Both the black color and the blue, and a surprising amount of the metal below it, was being rubbed right off. Besides that, activating this in the opposite direction of the throttle movement makes this awkward. There's a similar product on the market with a name that rhymes with bottle heister and that should be the only throttle lock you spend any of your money on. Quite a disappointment considering the quality of all the other fantastic Wunderlich items my bike is outfitted with.

RE: Trottle Locks for my K1200S BMW

Reviewed by Matthias from Glendale, AZ (3.6.2013)

I purchased the trottle lock kit for my 2008 K1200S to give my wrist ones in a while a break on longer trips. The 10 minute install was easy, but had to make minor trottle position gap adjustments on the handle. I install a month later some Heli handlebar risers and had no issues transferring the trottle locks to the new handlebar set. I like this type of locking design over the trottle meister version on my old 1150GS. It avoids an accidental locking of the trottle. I wish Wunderlich would also offer the trottle locks in hard anodized flat black.

Agree, using it is not intuitive

Reviewed by John Harpold from Arlington, VA (10.15.2012)

The device installed easily. I agree with several folks who mention its use is not intuitive. I have never resolved the jerkiness engaging and disengaging it. Maybe the folks who have no problem don\'t wear gloves.

Highly recommended

Reviewed by Jedi5150 from , (10.8.2012)

I've had this model of throttle lock on three different bikes, and today or tomorrow will be buying my fourth. I've had one on a specific bike for 25,000 miles, so longevity of the product is top notch. I've used them on several 1,000+ miles days on more than one bike. They are a lifesaver on long trips. I've read that some people think they are counterintuitive compared to throttlemeister type locks. Wunderlich got it right. By rotating the lock the way you do, rolling off the throttle is the opposite of the direction friction is applied. This is a huge safety issue for emergency braking, and this throttle lock is perfectly designed from that standpoint.

I've had one of these on my R1200GS for over years and 100,000 miles. It does exactly what it's supposed to. For me, this is a must have on any new bike. Over time, the unit gets dirty and required cleaning with a little WD-40 but once that's done it's as good as new. Well worth the investment.

I installed this last week and have used it on several ride. The install was clean. Directions straight forward. It looks cool and stock on the bike. Best of all it works exactly how it\'s supposed to. No problem turning it on with my right ring finger or pinkie finger. Great product. Can\'t comment on longevity but it was made very well.

Works fine; not machined well enough.

Reviewed by Glen Kahn from Denver, CO (8.16.2012)

Easy to install, works fine (like most and by the same principle). Like: blue anodized finish. Dislike or disappointment: there is too large a gap between the blue knurled wheel and the bar-end weight. Yes, you can slide the throttle grip-but that leave too large gap on the other side. This is just an issue of aesthetics and better machine work; better tolerances. AKS Engineering makes a better lock. The best I have seen is from Bob's BMW called Bob's Wrist Rest. Wow, really well made and looks and works great (for 1/2 the price). But, both of those are not available for the 650/800GS twins with factory hand guards. So, I am keeping this one--it does work fine.
