I mentioned in another thread that I had ordered the extra heavy bar ends from HVMP to try and quell the vibration in my N1K. I finally got a chance to install them and ride with them for some time. I just completed a 500 mile ride today and can offer my impressions about them now.
HVMP offers 2 options; heavy at 13.9 oz and extra heavy at 17.2 oz. I decided to go with the extra heavy option as they are significantly heavier than the stock ones as I wanted to have the best chance to reduce the vibes.
At about 7k rpm my hands would be tingling so bad that I didn't really want to rev it much higher and not for long. I had a decent sweet spot of about 4-5k where the vibes weren't too bad so this is where I normally cruised. With the 16T countershaft sprocket it worked out to be a good rpm for cruising at about 75 mph.
Well I can definitely say that these bar ends made a significant difference. In my preferred cruising rpm, it is almost vibe free. At 7k it is still there but greatly reduced. The vibes then drop away from 7.5-9k and it is almost as smooth in that rpm band as it previously was at 4-5k. Pulling on up to redline doesn't result heavy vibration as before but more like a tingling now. It now is actually pleasurable to run it all the way up the clock.
With the exception of about 7k on my bike, I can now choose any rpm and have more tolerable vibrations. At 7k I wouldn't want to ride all day at that rpm but now I don't have to shift around it to avoid. I can easily transition it now and not feel like I am holding on to cement mixer at a very high rpm.
This is going to be one of my best mods for long haul riding after the 16T sprocket and modding the stock seat. I added some very nice LED lights and had a chance to use them at night. I added 2 - 2800 lumen LED aux lights (driving beam pattern) and 2- 1000 lumen LED aux lights (more of a wide angle beam). I'll write about those in another thread as well as my impressions of the Pirelli Angel GT tires I just mounted.
The bar ends cost $66 and are worth every penny. I wouldn't even bother going with just the heavy ones. I don't think they would get the results you might be looking for and I can clearly fell the difference with these. They fit and finish is excellent. They do stick out a bit more than stock but I like it. I'll try and post some pics when the rain stops. Most of my ride was in the rain and wasn't a lot of fun but I got to test out a lot of mods on the way.
