I'm quite sure my 1985 Honda Nighthawk 750 S had hydraulic valve adjusters. Can't remember what the redline was, but pretty sure it was around 10,000 like the Tiger. Awesome bike for it's day, including shaft drive. Maintenance was indeed minimal, but you did have to balance the carbs once in a while.

I think you and I are probably similar, in riding styles and experience. I use Ferodo, on everything that I personally ride. Their Sinter Grip ST is a pad I think you should try. They can be a little noisy, but, they're very aggressive without the need for a lot of temperature. If that doesn't give you the lever feel you desire, you can easily swap a takeoff master cylinder from a more sporty Triumph. I'm not sure on all the piston diameters of each bike, but, that's where I'd be looking.

Definitely, nice bikes, even today.

I no longer work in a dealership. Otherwise, I could verify exactly what it had. A quick web search shows that it had rocker arms, but, can't quickly find anything further.

While we are on the subject of brakes I have noticed my fronts produce a lot of brake dust. I'm still in the break in period but do not remember my other new bikes producing dust. Do these pads just produce dust at break in and then clean up later? Or are they just the cheaper ones that always produce lots of black dust?

Yep, my 650 Nighthawk from that era had hydrolic lifters, tensioner and shaft drive. Ran like a scaulded dog and never had to do anything to it.

I'm not exactly sure what the compound is. But, organic pads are the dustiest and least aggressive. Semi-metallic are less dusty and quite a bit more aggressive. Given the intended use of the XC, they're probably organic. If they're too aggressive, people always complain.

They should be but according to the Triumph manual they're replaced on a service. I certainly won't be replacing them every time when I start doing it myself.

Not true. The Honda CBX750 in the mid '80s had Hydraulic tappets. http://en.wikipedia.org/wiki/Honda_CBX750

Look under "Power train".

Thing is, IMO, you don't want an aggressive front brake on a bike that's likely to be ridden on dirt. I think they got it right for the XC at least. That slight "mushy" feel gives the brake, er, feel. e.g. I can drag the front going down loose hills using my "brain ABS".

I have a KTM woods bike and it has excellent brakes with strong initial bite. The brakes feel like overkill on that machine. I adjust to them quickly and appreciate their strong, save my arse, initial bite stopping power. I wish my Triumph had that same inital bite. I'd rather have to back off, then feel like I need to squeeze the juice out of them. They have a feeling of being undersize for the machine to me. I'm sure there is a reason for this like you mention but I wish they had a bit stronger feel to them.

Try EBC HH pads.

What was the redline of that engine? I'm guessing the Honda was at the absolute limit.

As mentioned, I'm not exactly sure of the layout and design of that vavletrain. I know it has rockers, which may contribute to Honda being able to run hydraulic lifters. The triple is shim-under-bucket. I'm not sure if there's ever been a bike with a hydraulic valvetrain and having the cams directly acting on the valves.

See this post and "intended purpose". Different strokes for different folks.

The Red one on the right was mine. Believe me when I say that engine was a peach and no slouch. Nearly as good as the Tiger. Wonder what happened to it?
