KTM's 790 obviously does not get the factory's wonderful clutch baskets. ::) ::)

"If you are looking for the engine profile that Honda copied in 2021, then this is it."

Reading how some bitch and moan about KTM's failures, I thought I'd share just how much more advanced their bikes actually are.

Allow me to summarize:
  • lightest: 15 pounds lighter than the YZ450F and 18 pounds lighter than the RM-Z450
  • strongest brakes: The “Big Four” Japanese brands have been throwing on 270mm rotors, new brake pads and calipers to try to keep KTM’s Brembo brakes in sight. They are still behind the curve
  • most reliable clutch:  From its CNC-machined steel basket (with the primary gear machined into the basket) to its Belleville washer (instead of six separate coil springs) to its rubber-suspended cush inner hub to its self-adjusting Brembo hydraulics, no clutch on the track can take the kind of abuse that KTM’s can. This is the dream clutch of every clutch abuser in America
  • braided-steel brake lines
  • Pankl transmission: No other motocross brand offers a transmission built by a Formula 1 gearbox supplier. The metallurgy is a step above what other brands offer
  • Connecting rod. also made by Pankl
  • Electric starting. KTM has had electric starting on the 450SXF since 2007. You might be thinking, “So what? Almost every other 450 has electric starting also?” Yes, they do, but KTM knows how to do it without adding 5 pounds of extra weight.
  • look no further than Dakar to see how reliable these motors are. And if you think the 450RR has a different motor, look at the breakdown I did earlier, where I listed all the similarities

The list goes on, go read for yourself

Hardly cutting edge technology, what makes you think a 5 pound electric starting system on an efi engine is cutting edge?  BTW, KTM had issues with their ES system until circa 2014.

What if I told you American and Japanese engineers from Arctic Cat and Suzuki, respectively, invented an electric starting system, in the early 90's, that weighed mere ounces and did NOT use a battery?  It was labeled Batteryless EFI and was released to the public on the 1997 Arctic Cat ZR580.  The first pull of the starting rope energized the stator, the second pull started the engine.  It was a genius and very reliable system that weighed next to nothing, compared to 15-20 pounds with conventional battery, ring-gear, solenoid, starter, etc., systems.

If violent crime is to be curbed, it is only the intended victim who can do it.  The felon does not fear the police, judge, nor jury.  The felon must be taught to fear his victim.
