Grips and Bar Ends for Renthals

I'm going to be putting some Renthal Road High bars on my 919 this spring. I'm 6'6" and from what I've read the Renthals will give me a wider grip with less pull back (Easier on the shoulders) while keeping me upright.

Any recommendations on some grips and bar ends? I've got stock mirrors and I think I'll keep those on. I mostly do pleasure riding, commuting, some long trips. No track days yet so aggressive posture is not a concern right now.

Thanks for all the help. This place is great.

I only have stock grips, so I can't really comment on those. For bar ends, my motovations work quite nicely to keep the buzz down.
Oh, and welcome to the site!

I still have the stock grips, still like them, not changing them.
I have Renthal ULs.
I used the LSL bar ends, nice, simple, clean looking, fit perfectly.

I don't have Renthals yet but plan to add ULs over the winter. I'm planning to use the standard Renthal bar ends. They seem to have the same sort of extension beyond the end of the bar that the OEM bar end weights have. That extension of maybe an inch is comfortable for me.

I have Rental UL's on my bike, and put some nice ProGrip grips on it...and bar-end mirrors. I've been very pleased with this setup for a number of years. Go with what looks & feels good to you!

Someone on this forum measured the OEM bars and made a sheet for comparison with the optional Renthal bar designs. I've thought this was pretty good so i wanted to re-post it...

Hopefully that attachment shows up in this message. LOL

I have found the BMW grips to be very good. I am using Renthal bar ends.

Thanks everyone for the advice and Mark919 for the chart. The chart confirms what I had read in much less uncertain terms. The biggest thing I'm looking for in new bars is a broader set to match my shoulders with less wrist pinch angled inward towards my body. It looks like the Road Highs will do this best.

Regarding the bar ends, I like how the stock bar ends match the diameter of the grips so that you can easily rest a portion of your hand off the throttle. The Renthal ends seem to be only the diameter of the bars. Any suggestions on 7/8 bar ends with greater diameter to match the grips or is there an advantage to having smaller diameter bar ends relative to the grips?

Just about any of the renthal bars will give you exactly what you're looking for. I'm 6'3" with all my height in my torso and the stock bars killed me with the bend in... Road Mediums are almost the same height and pullback as stock, but the bend is so much nicer... I would assume the Road High's are even better if you want a little more sit up position.

Those wont work unless the stock dampener is put in the renthals. Which would need further modification to the renthals. I.D. is 14mm or 13mm? Smaller than stock anyways.

Right, I thought that was the issue. When you switch to Renthals, the stock bar ends won't fit. I seem to remember seeing something on here about someone modding the stocks to fit with a fuel hose? If anyone has suggestions for how to make the stocks fit with Renthals, or if this is even a good idea, I'd appreciate the help.

The stock dampeners are bigger than the the renthal Inner diameter. You could drill the renthals to accept the bar ends!

This seems like something to try before spending more on bar ends.

I thought one of the benefits of the Renthals was reduction of vibration. Will new bar ends make an appreciable difference or is that just making an unnecessary modification?

So there are quite a number of handle bar manufacturers out there that make a variety designs that will fit on our 919's... They are aluminum and steel and have different shapes and wall thicknesses. They all will have different vibration characteristics. No doubt the Renthal High bar will be different than the Renthal UL.
The purpose of a weighted bar end (like the rubber suspended OEM bar end) is to change the natural frequency of the bar assembly so it isn't amplified by the bike's vibrations. If you were to remove the OEM bar ends from your bike, as it is now, i think you'd find that the bars would vibrate quite a bit.
If the bar end you select for the new Renthal bar is just a bar "end" then it's probably made out of aluminum and won't ad significant weight and won't help if there is a vibration issue. But the Renthal High bar may be ok without adding a weight. I don't think you'll know until you try it. (Or unless someone else on this forum can give first hand results of their own with Renthal High bars...)

Just my 2 cents,
Mark

Here is my setup with Renthal High with bar raiser

I'm using the old extra weights that I had on my old stock bars

but I had to enlarge the the Renthal's interior diameter to make it fit.

BTW, I did not cut the bars so my total length of the bars is:

I'm happy with the setup...

Bumping this to get some group thoughts and recommendations.

So I've got the Renthal Road Highs and some Pro-Grips that are closed ended but will soon be open ended. I'm waiting for some warmer weather before I mount them. I know the stock vibranators won't work so I found these:

Anti-Vibration InsertsFasst Company


Do I even need these? Do they make that big of a difference? These are compatible with the Renthals and I've been told work quite well (Plus aren't too expensive). I know I could easily modify the stock bar ends to work with these vibranators but then I started thinking about bar end mirrors and having the option of putting them on down the road. If I want to have the vibranators in the new bars, I could:

1) Mount the vibranators with bar end of my choice in the Renthals but leave a portion of the end of the Renthals sticking out so that I could put a clip on mirror on the bar.

2) Mount the vibranators with bar end of my choice in the Renthals, have the grips out towards the end of the bars, and swap in a bar end mirror (If I choose to) that mounts internally. Would I still be able to use the vibranators with this arrangement?

So if I bought something like this:

BLACK-3-ROUND-2-ROTATION-FOLDABLE-7-8-HANDLE-CLAMP-ON-BAR-END-MIRRORS-PLUG

I know I could use it as a clip on (Option 1) or mounted on the end of the bar without the vibranators. However, could I kludge that to work with the vibranators (Option 2) on the internal mount? The goal here is to maintain flexibility with what I want to do and I don't want to mount the grips inward to accommodate a clip on down the road if I never end up getting them. So I think Option 2 would be my first choice, I just want to know if it's even a realistic choice.

Anyone have bar end mirrors with vibranators? Thanks a lot for the help.

Renthal has a nice medium grip that is nice and squishy, it felt great on my hands. Also, Renthal bars are pretty narrow on the inside because they are really thick, so you are probably going to want to end up getting some Renthal bar ends to match. After having no luck on ebay finding the diameter I needed I just finally splurged for the Renthal anodized black ones on the Hornet, and Blue ones on my project Hawk.

Also, since the bar is wider and you have more room to clamp, instead of doing bar end mirrors, take those bar end mirrors and mount them inboard on the bar and under, somewhat of a Supermoto style. You'll have more of a chance seeing stuff from behind and people would constantly be hitting or knocking your mirrors out of whack when they walk to close to your bike.

Dan, It looks like those Fasst Co. vibration inserts would mount tightly to the bars. (Assuming they're set to work w/ Al bars) With that, mounting bar ends or the mirrors to that base should work ok.
I wouldn't do your option 1) with the bar itself protruding to mount the mirrors.
In the end there is very little risk to any of your arrangements. And that's where the flexibility of this set up helps out - you can always change it over.
BTW have you decided how to drill alignment holes in the bar to position the levers? That's one area that might take some care to do well. I'm sure there are some good references somewhere on this forum for that too.

I also like Rob C's suggestion on the inboard mounting for the mirrors. I used one CRG end mirror for a while and found that I had to constantly adjust it - more trouble than it was worth.

rpcraft, is this what you're talking about?



Has anyone mounted mirrors like this? Are they very functional? I'd imagine I'd be looking at my legs and hips all the time, plus it's a long way down to look, ie tougher to make a quick glance.

I think I'll just stick with either bar ends or the Aprilia mirrors.

Mark919, I was definitely going to be drilling for controls. I have seen a lot of references on this site, but I think this one is the best:

Credit to HrcRacing27. It looks pretty straightforward and easy enough to do as long as once I get things placed I measure 2-5 times and drill once. As the great Ron Swanson once said: "Never half ass two things, whole ass one thing."

Thanks for all the help and suggestions.

Thanks guys. I'm not a systems engineer, just an electrical engineer (We patent attorneys are uber nerds). There's a lot of things I need to do to the bike this Spring and I'll be sure to document it all. The current plan is to invite a fellow bike owner over to help out in exchange for some food and brews. Pretty good offer right?

With the offer of some brews I think you'll have locals lined up at your door. I have seen a few 919's running up and down Woodward...
