Canadian Boy

listen man, you bought a bike from a shop that said Taffy rebuilt it?? youre blaming taffmeisters for dirty oil and mouldy air filter?????
are you insane?????
I've dealt with taffmeisters on several occasions, amd they knew husaberg better than anyone else. not to mention they ship to canada faster than canada ships to canada😕😕
sounds like you got f______ed cause you don't know your ass from a hole in the ground..
if I were you, with zero mechanical abilities, I stick to buying brand new😂😂😂😂😂😂.

Read all the posts, all of them, especially the one where he shows the link from Taffmeisters and explains that was who he got the bike from!

Wow! Stunning post!

Like the other guy saying read all the post , link and picture I display ...he probably used it for a while before he decided to selling it ....shipping time ''I don't care '' nothing to do here ...how about can chain tensioner? And head?

I been racing since I was young..from a 50cc ciao to 530 ktm ...never had usaberg before...I even had pit bike and they last me more then 6 hrs lowest hrs i had in my life was from pit bike 25 hrs (blow) ...and 30 hrs on piston on supermoto but you get easy 60 ....max hrs i had was from ktm 530 160 ...i know people who bring their crf to 120 hrs before piston other blow up at 50 it all depends on how you treat it ...oil change/air filter are the key

I would like to see the internals of a KTM 525 with 40k on it lmfao.

As for the Porsche. This is a totally different machine lol. It is not a single cylinder and works much differently. The Porsche will not run at temps the Husa does, will not take the load the Husa does and is designed to with hold the km's that it can. The Husa and or KTM is not designed to do this. They are built as High Performance Racing machines unlike the Porsche that is built as a daily driver. Compression, cooling and many more factors. Load and torque ratio ect. To move the husa is allot different than moving the Porsche. Torque to weight ratio has a big factor. Do you think that the RPM of the Husa is the same as the Porsche? Not even close. It has to put force down to make it move with a fraction of the horsepower and torque. It will also work a million times harder to maintain 100kmh than the Porsche will.

The rings are working more, moving faster and wearing faster than any Porsche designed. A stock 2010 911 Carrera puts 385hp down at 6500rpm. A normal everyday driver will pull 3 to 4500 k shifts at most. Pull 15k shifts in this Porsche all day long and see what happens, but you don't get arount the block twice without a catastrophic failure, bet the Husa outlasts it. LOL

Basic mechanical math my friend.

Must have imagined my first brisbane to cape york 7500km trip on my ktm 525exc. it only had 7000km on it before I started.
ktm 570 motard was re-ringed at 150 hours for performance purposes. I wanted every one of those 62hp way back when.
Anyway, Did a quick search came up with half a dozen pages on longevity. So it wasn't just me getting lucky. Have one riding friend on a berg with 8000km, and hasn't had to adjust the valves yet. so you keep laughing.

I am happy for you to continue your servicing/rebuild regimes. So are the people that sell you the parts/labour.

Oh, and it is interesting that you think longevity of rings is based on torque to weight and RPM. Yes the forces increase non linearly,as rpm increases, but an engineer would tell you wear is a function of friction,abrasion corrosion, and scuffing. Keep them under control.....

Back to the thread. Canadians seem angry today

I don't mean to hijack the post either. But I have seen a KTM 400 exc with close to 40,000 klm's on it getting its first top end job. Bottom end was still in spec.

There is a bloke on KTM talk who claims to have gotten 111,000 miles out of his 520 before rebuilding it. He did go through a lot of water pump seals and cams he claims.

It all depends on how you ride, your maintenance regime and luck.

FE350

LOL, Yes it is based on friction but also friction is created the hotter it gets the more friction the more wear, the more rpm the more friction and so on. Weight vs Torque also come into play as this creates load on the engine and with load is friction creating wear. lol. So when a machine is working to a maximum load as per torque, weight and other factors it works harder and thus by working harder wears more. As for the work, parts and labour, I am a technician who maintains my machines above OEM specs so I will do nothing but benefit ensuring my machine is maintained to the fullest. Yes I do believe the mileage is possible, but allot of wear will be present as well. It is fact that valve seats wear and a machine that is untouched will not perform to one that is within spec. No possibility what so ever that valves could have no wear,rings and cylinder will also have wear even if you use snake oil in the engine. I have seen machines that have sat a half century and fire right up and work, but this does not mean they are running within spec and or don't need to be rebuilt to spec. Just because the machine runs and continues to run does not mean it isn't worn and maintenance is not required. If you ride the KTM to the purpose is intended such as racing as the exc is designed. It will be worn for sure and when in is operating the load on the motor will be at continual peak. If you put around the streets then it will wear less as it is not being worked. Allot of factors are involved. It is also huge risk running a machine not within spec as a huge failure is more likely to happen.
Preventative maintenance replacing little parts and spending time vs parts is much better than replacing the whole thing.

I am sorry I didn't get into detail on wear and engineering when replying prior as I was unaware you were an experienced engineer with the Porsche comment you questioned.
