Dot 5.1 is compatible with 3 and 4 and is higher boiling point than 4 without being silicone based. It is compatible in most instances thought i would ask here. Better brake performance is always a good thing.

High temp maybe needed on track day. But for general riding highly doubt you would see the benefits, unless one likes to ride in such away to get the brakes up to race track temperature all the time.

You expressed "better braking performance is always better". How is that not an opinion!!!!

Try to think of this as a conversation you would have with some fellow riders while sitting around a table drinking coffee, or sitting around a campfire having the beverage of your choice. You ask your question about brake fluid and one of your fellow riders (call him Charlie) asks about your reasons for the questions. Certainly Charlie's question is not an answer to your question, but how do you respond? One choice might be to respond in a friendly manner and answer Charlie's question; another choice might be to respond to Charlie in prickly sort of way that shows your anger because of the question being asked. Being friendly will likely lead to the discussion continuing and perhaps a more direct answer to your question. A prickly response will lead to.... well we know where that will lead.
Don't write us off as just a bunch of jerks, please. This is perhaps one of the mellowest forums there is concerning motorcycles. Despite your frustration in how your question was answered, the great majority of our members are friendly and helpful, but even the best of us has bad days. This is also the place where you can find a great deal of info about your bike and help with diagnosing problems. I think you have a Hexhead. If that is true, then you have a fantastic tech library available in the Hexhead sub-forum. Hope to see you around.

Yes getting the 2011 today. 9k miles. In great shape, first business to do all the fluids. Then a couple of recalls and then tires. Then ride.
As to your response. No one asked me why I wanted to do it. They said unless you are racing it is not needed. The higher the boiling point of the fluid the better, i don't care how you ride. It will slow the onset of brake fade. I have ran 5.1 in my previous Dot 3/4 bikes with no issues. But none of them were abs equipped. Was hoping someone might have already converted to 5.1 and had experience with it.

Au contraire. Look at the very first response, post #2 where I asked "but why?". I was sincerely asking why you wanted to use 5.1 when DOT 4 is in spec and usually sufficient.
And only peripherally related: some folks believe that premium fuel is better when regular is specified and some folks think that Xw140 weight gear oil is better when 80w90 is specified - neither of which is true. So I sincerely wondered why in your specific circumstance DOT5.1 was needed.

There are DOT4 fluids that have wet boiling points as high or higher than some DOT5.1 fluids. This chart might give some useful comparisons:

I was not going to say anything. But the more I thought about this, the more this type of response is unwarranted. Evidently you have taken a personal offense to me offering an opinion, whether it was asked by you or not. It's only an opinion, I did not attack you in anyway. You could have easily ignored my opinion. But no, apparently you felt I deserve a slap in the face.
So at this time. you will never hear from me ever again.
My face is still stinging from the slap. I hope you are happy!

Whoa Whoa, slow down. Enough with the personal insults.
You are on the wrong site.
You should hang out in the Basement on Adv Riders.
If all you want is a direct answer with no discussion, Google is a great resource.

When a question gets asked on a forum many readers want not just the narrow answer but also to explore the topic. That is what foruae provide.
How much air pressure should I run in the rear Michelin PR3 on my R1100RS? That might elicit the comment that a person has had better mileage using a Metzeler tire (pick your model). And somebody else might add that Avon (pick your model) are on sale at (pick your vendor). Finally somebody might add the book says 36 psi but I like 40 psi better. That is what a forum does and is.
