NC750x Seat comfort - Vibration

[charkmandler]

Like many riders of NC750x's I've tried a few different seats and still suffer on any rides over an hour. The latest seat is a copy of one on another bike that I know is comfortable. With this new seat I can ride for quite a long time at low speeds where there is not hard acceleration but once above 50mph I'm suffering. This got me thinking that the numb / bruised bum could be due to the type of vibration of the bike.
I do about 20,000 miles a year and a lot of rides are just sitting on motorways at 70mph to look after fuel. I noticed that on the occasions I have some fun and ride harder I do not suffer so much - this could be the fun factor and changed riding style for fast / harder riding. I also noticed when riding in speed restricted areas at 60mph in 6th at the seat becomes more uncomfortable.
On 'commuting' rides I tend to change in to 5th at just over 40mph and 6th at just over 60mph. Based on that I upped the mph by 10, so 5th at 50mph and 6 at 70mph but sitting at 80mph on the motorway. With the changed vibration I find that while the seat problems are not cured they are better. Sitting at 80mph on the motorway defiantly seems to help.
I'm coming to the conclusion that its the inbuilt 'v' twin vibration built in by Honda engineers that is the problem more than seat design.
It would be interesting if other riders could experiment with the revs they sit on motorways at and let me know if they help.

I don’t really notice the vibrations at any speed. However, one thing I noticed is that wearing protective clothing such as Kevlar jeans or motorcycle overpants helps quite a bit. If I’m in regular jeans my limit is 30-40 minutes. Overpants I’ve ridden about 2 hours and that was limited more by gas and my body position.

Mine is a 700, not a 750. While the NC isn’t the smoothest running bike I own, vibration does not cause any discomfort at all.

Another factor in seat comfort is handlebar position. The whole rider triangle is important. I found 3.2 inches of bar rise actually increased the seat comfort.

Vibration was not something that I noticed until I started analysing it. Tried different types of clothing.
I don't suffer on other bikes. A ride that I frequently used to do was 300 miles - work - and then ride back in the same day. I could not do that on the NC.
Experimented with bar position.
As many riders have found the seat so uncomfortable and some ended up changing bikes I'm looking further than just the seat. Vibration does come through the seat.

I guess it’s all subjective. At 6’2” I find the bars too high for comfort. I’ve purchased a bar that’s a good two inches lower. Hopefully I’ll find it more comfortable..

Update. I think its a back tightness problem I didn't realise I had. Doing some Pififormis specific exercises and this is reducing the numb bum effect. Anyone suffering with numb bum I suggest going on YouTube and looking up Piriformis exercises - not just stretches but strengthening.
