Took the old pumpkin out for a rip and forgot how light this bikes feels. I hadn't ridden it in over year. It also turned so freakin' good! The bike I've been riding all year is KX450SR.  I enjoyed the KTM so much it's motivated me to not only keep it, but give it some love with new plastics/graphics etc. 

Which brings up the question my buddy and I were asking ourselves at the track. At 220lbs, was this the lightest stock 450 ever made?

The 2018 had claimed weight of 220.9 lbs dry. The next generation was 234lbs I believe.

I still have my 17.5 Factory edition  pretty much the same as 2018 and love mine. I’ve ridden the newer ones and somehow it didnt seem the same. Still running great too150 hours just so solid

Sheesh, that's actually tough to answer right now. I'm still in shock how good it felt. I was convinced I would never ride it again after getting the SR. The ktm just felt so nimble and fun to ride which made it feel fast. I'm curious to see how my lap times would compare to the SR, which is very stable and deceivingly fast especially on a longer more wide open tracks.

Nice, good info.

Sometimes old friends are best friends right? The more familiar you are to a machine the more comfortable it is, perhaps you just have a lot of hours on it from previous seasons, used to it? I always am apprehensive about getting a new bike, adjusting to it, setting it back up, when the old familiar steed was just so comfortable and familiar. And I think newer bikes are getting stiffer and stiffer, frame wise.

That's dry weight which some manufacturers spec as all fluids except gas, some spec it as no fluids at all. MXA weighed it with all fluids except gas and it was 222lbs. It holds 1.85 gallons of gas, which premium is ~6.3lbs per gallon so 11.66lbs. That is 233.66lbs ready to ride without any additional accessories. KTM used to be the worst about real world weights...

That 2018 frame was the business!  I still kick myself for selling my 350.

I have a 23' 350, but keeping my 22' 350 because I feel like the old bikes were the end of an era.  They were like 80% the size of everything else and so nimble.  

I'd hang on to that 18' 450.

Your number sound legit based on my experience.
I weighed my buddy's 2018.5 450 Rockstar Edition back when it was new and after he installed a spring fork, etc.

I have a '23 MC350F with 3.1 hours on it. When new, it was basically the same weight as my '19 YZ250.
I've since replaced the airboot, added a plastic Acerbis skid plate, a stock muffler without a cone-baffle, grip seat, map switch and one of my KYB spring fork conversions...   Basically, I added five or six pounds of shit that I probably can't live without.

(I'm taking a moment to weigh both right now, but through the magic of time travel, the bathroom scale weights are below)

Both bikes are full of fuel and ready to go to the track this weekend... 
[$29.99 mechanical bathroom scale]
'19 YZ250 = 128lbs   (110 front / 118 rear)
'23 MC350F = 132lbs    (112 front / 120 rear)


That's pretty damn good for a fuel injected four stroke with a stupid battery, a rat's nest of wiring and and an electric starter!

I wonder what it actually weighs, ready to ride, in real life.   MXA probably captures the best weight data...  I bet it's in their test, if they were putting those articles on the internet by 2006...


We do this stuff with all of our bikes and it's a real eye opener:

Put a bathroom scale on a motorcycle stand and lean that old Honda over so the end of the bar rests on the center of the scale...  Note the weight.

Do the same with any last generation 125, then a 250 two stroke, a 250F and a modern 2016.5+ KTM...

The 2009 - 2011 KX450F vs the 2012 KX450F is a great example.  It felt like Kawasaki took a cinder-block out of the gas-tank on that 2012 model.   These bikes keep getting better, for the mostpart.

Both bikes leaned over with the throttle grip on the bathroom scale 18.5" above the level concrete floor:

'19 YZ250  = 75lbs
'23 MC350F = 79lbs

There are a lot of people that have very plainly put it, the 2018 KTM’s are the best they’ve ever made. I had an 18 250 SX and logged a substantial amount of time on, but eventually fell out of love with it because of how substantially different the bike felt from my newer models. 
 

I always felt marginal on my 21/22’s, then felt a significant handling upgrade in my 23’s. 
 

On the topic of weight, I have nothing to contribute. Carry on.

Still love my 2016 KTMs. Chassis on these works so well for the average rider when setup correctly.

2018 450 was the best 450 I’ve ever ridden to date. I think the 2018 lineup was KTM’s best lineup to this day as well. 
 

That chassis was developed around Dungey, maybe he needs to jump into the development side of things.

I feel better about staying on my vintage bike, 17 FC450. Suspension/Bills Exhaust/Twisted ECU remap. That stiffer frame thing is the Supercross influence which 99.9% of us are never going to do at a pro fast level. Remember CW2 wanting to go back to an earlier frame version outdoors?

Of course. And I guess I should keep my '17 350sx w/ spring forks, linkage, exhaust. All that's left is a Vortex

Never understand when SX stuff makes it’s way to production bikes. It’s silly.
