    Interested in a single front rotor conversion. Any details as to what was required to retain good brake feel? Did you need to swap the front master cylinder? If so what did you go with? Thanks.

    Brembo radial master....man I think it is a 15mm.

    Rottweiler has them and knows the correct size

    Feel is spot on

    I used a 13mm master cylinder from a 690 Duke. It retains the same leverage ratio as the OEM 18mm master has with 2 calipers. Has the same 2-finger effort as stock.

    You definitely need to swap the MC.

    As noted about KTM already has a fitment, the Brembo single M50/Radial master on the 690 Duke R......after that its just a matter or measuring to get lines that remove the crossover, so you run straight from the ABS valve to the caliper.

    i was ribbing a little bit about another 100, but i would really like to see SOMEBODY play in the sandbox with the ol' highland 950. i mean if they could do it 20 yrs ago it should be able to be done today.

    having said that, your goal is a good one, there no reason a bike that was built to be a lightweight off road performer should be heavier than an older bike built for the same purpose.

    KTM is spitting out innovative bikes, but not better bikes

    This sounds like the opinion of someone who doesn't own a 790, and doesn't want to be tempted into buying one. All people could talk about before the 790's were released was what it would weigh, as if that is the only metric that determines how it performs. Well, I love my 950, but the 790 is better in every way, including it's weight. It's been completely reliable for over 6000 miles, and my 950 has been collecting dust for months now.

    my views have nothing to do with ownership, and you know i dont own one from our previous engagements. let it go buddy.

    i'm not making comments that the 790 doesnt perform well, or that it falls short,,, your injecting that nonsense into my words yourself.

    i'm mearly trying to have a conversation that it seems modern advancements in materials and manufacturing should be able to produce a bike, like the 790, being both physically smaller and having less displacement should weigh less than the 950se to begin with, and nowwhat for example should have a sub 400 lb bike by now.

    I mention the highland 950 because that was an excersise in a rediculous bike, light, fast , very long travel. Its something that may never be produced again, but the fact that it was produced 20 years ago says something.

    Engines are built a bit lighter due to modern computer aided design but what other material advancements commonly used on production motorcycles have changed between a modern production bike and one built 15 years ago? None that I know of. More government safety and emissions standards is all I am aware of.

    The 950SE/Highland were dirt bikes with big honking motors. The 790 is not a stripped down dirt bike with a marginal subframe and short fuel range. Does that make the old bikes better than the new ones? Depends on who you ask.

    If weight is the golden measure my guess is that if someone wanted to put a peanut tank on the 790, strip it of all government mandated emissions equipment, and put a subframe on it not suited to two up or carrying heavy loads over rough ground and make a few other mods to make it a dirt bike it would easily outclass the older 950's by using weight as the measure, all without any unobtainium exotic materials.

    Well I am running out of places to strip meaningful weight.

    The Highland was bad ass .. derailed by a plane crash or many of us would probably own one...poor fuel range though

    The SE was the standard but has been bested by the handling on the 790..

    My 790 is still 10lbs too heavy but I am tapping out and calling it good as it is just soo nice to ride...will get the rottweiler intake when available and that's about it

    Would be kinda fun to have a number plate only on the front but it isnt going to be practical

    I assume my sub 400lb dreams are dashed
    402 will have to do hahahaha

    We all know its just a number and there are other factors at play, but its the topic of this thread and i'm just making conversation.

    30 lbs stripped off is impressive!

    You're so close to sub-400 w/o gas!
    Is that with RallZ tires? (They are super heavy)
    Have you laid a piece of vinyl across the frame rails and done away with the seat yet?

    :D

    Dunlop 908 and a rally scorpion up front with HD tubes...

    Would like to take weight off the front...maybe no front brakes hahaha 6 more lbs...

    I will probably lose the keyed ignition as I do on my 500s and install a hidden switch. Not for weight but for no key convenience..but you lose weight accordingly. Since the last weigh in I replaced the stock hoses with Samco and lost the stock rear luggage plate.

    New skid plate will add weight....

    ive seen the T700 on the scale from an owner, its weighted to the rear about the same as yours is weighted to the front.

    have you identified whats there that you might be able to move instead of remove? for example, the 9x0 bikes responded VERY well to moving a couple things from ahead of the engine to behind of the engine.
