Tuning and modding » HVMP bar ends - a "gold medal" winner

I just received a set of HVMP bar ends for my RS today (fast shipping...4 days). Installed them in minutes, then went for a test ride. Very impressed, and one of the best "bang for the buck" mods for the RS. In the rpm range I normally "cruise" in (4,000-5,000 rpm), the vibration was reduced significantly, so much so that cruising felt more "relaxing", if that gives you an idea. I also ran the rpm's up to around 8,000 to see what's what at that level, and was really impressed with the reduction in vibes. The bar ends are longer than the OEM ones and weigh twice as much; the length is nice, for I can put the RS in cruise control and rest my palms on them in real comfort. For a bit over $100 (I chose the black ones...$15 additional), this is (in my opinion) a "must-have" mod for the RS. HVMP is a family business turning out high-quality products and they deserve their stellar reputation.

So far on my RS, I've made 4 modifications, each costing just over $100, and each has made significant improvement in the RS:

1. Mud Sling rear protector
2. Puig Touring Plus windscreen
3. MRA "x-creen" deflector
4. HVMP weighted bar ends

Have a great day, all...

Interesting. I haven't noticed any vibration that needs addressing on my RS.

The best bar ends I had were the standard fitment on a Triumph I had. They were a 2-part design with rubber separating the inner and outer metal parts to dampen vibration.

Another solution I heard of with tubular bars is to gum up each end with silicone sealant and load the sealant with a heavy ballast such as lead shot.

From the Barsnake site ("Rider" magazine review - https://www.barsnake.com/index.php/product-reviews):

"The Barsnake can only be installed in tubular handlebars, and only if there are no control cables or wires running through the bars."

That might suggest that on the RS clip-on bars it's a non-starter.

Did a 75-mile evening ride up and down the mountain canyon after the morning install/test ride, to ascertain if my initial impression of the HVMP's held up on a longer ride. Reduction of vibes confirmed. Happy with this mod.

did you not read my post in the context of the one I was replying to i.e. an RS with the factory fitment of flat R bars or the Wunderlich alternative?

Adding weight will alter the resonant response of the structure, but that's different than Damping which dissipates the energy within a shear layer (the two-piece triumph bar ends, the lead shot or Bar Snake). Achieving the damping without adding weight is (usually) the desired objective.

OK...so can you suggest how it might be applied to the RS, by BMW at the factory, say? Or better, at the owner-level?

BMW would suggest you buy a GS or RT with a Telelever front end rather than fit a polymer sandwich where the bars meet the top yoke.
