Sometime this week I believe. It's on his Instagram.

I had an 08 crf450 that I rebuilt and rode from 2017 to 2020. I also got a 19 kx450 the beginning of 2020. Vet A level rider-the biggest difference was more chassis comfort on the kx. Power-the Honda was actually better. I ended up making the kx feel like the crf. Suspension was better on the kx, but both revalved and setup properly it wasn’t a huge difference. The kx450 felt like a refined 08 crf450 to me and partially from knowing what I liked and applying it to the kx. I kind of wish I wouldn’t have sold the crf450. It was simple and did everything well. I believe anyone could be competitive today and have fun on that era bike.

I believe the 19' KX450 frame is a copy of the 07'/08' CRF450 frame. I remember Keefer saying that Kawi used that frame's geometry and flex characteristics as a reference. Maybe it's not exactly the same but I think it's pretty close from what I remember hearing. I had an 05', and 07', and an 08'. The 07' and 08' were awesome and that was at my peak riding and racing ability. I felt so confident on my 07'.

Same here. And unfortunately, I traded in my totally dialed 07 on an 09 KX450, which was a brick with an engine attached. Apparently the memory of trading in my 96 CR250 on a 97 had worn off…

I had a conversation with RC on this exact topic and his response was very interesting.   I'll respect his privacy for the majority of the conversation when it comes to brands, but for the most part RC said the only game changer from early bikes to the current bikes was EFI, especially for supercross.  He said other than EFI, the old 4 strokes could be just as competitive and a top rider could ride around any difference in feel/weight/geometry, etc.  I guess Roczen has kind of proven this for all the Suzuki bashers who claim the bike hasn't changed in years.

You might be surprised to hear what RC's favorite factory bike of all time was.  If you ever get a chance to talk to him, ask him.

I had a nice, low hour ‘08 RMZ 450 that I bought and rode regularly in 2018 and I rode it back to back with a friends new 2018 (essentially the ‘25 model) and the ‘08 hands down handles better and has better suspension IMO. The engine has improved on the newest gen and the ‘08 engine just did not rev out. 

In fact, I now have a 2012 RMZ 450 with 11 original hours and I feel that I can ride it just as fast and competitively as any newer 450 that I’ve ridden. ( I raced one in ‘12 also).  It is my favorite bike of all time no question. I had an ‘08 CRF 450 back in ‘08 and I really liked it as well. I would love to ride one again. 

I had an 05 CRF450R and a 12 RMZ and loved them both. The 05 had a ridiculous motor for the day, and the RMZ had a perfect Vet motor and would turn under anything else. Miss them both!

I still stand by my 03 and 05 CRF’s with a jetting kit were two of the best bikes I’ve ever owned and lap times would be same if not not better than what I ride today (last gen YZ450f).  I refuse to believe my Yami can turn better than my 05.

I’m in the minority.  I’ve owned CRF450r models 05,06,08,09,10,12,18,20WE & 23WE. 

The 05-08 models were definitely ahead of their time back in that era. 
IMHO a well set up 09-12 is a better bike.  The 18 + are a notch above.  
I really liked the 09-12’s that I picked up a low hr. 12 model to keep in the stable. 
It will be interesting to see Keefer’s comparison.

The 03's in my opinion were pretty mellow, but because of that you could ride it hard for way longer. It almost felt 250F like the last time I rode one. Very very easy to ride!

Not to derail too badly, but I had the 06 CRF250 and remember having to get some crazy Tokyo Mods carburator modification to eliminate that low end bog it had.

My son had two 08 crf 250s and the 450 the bog is real in the 250 we had to use an R&D float Bowl with the leak jet blocked off and adjustable to get rid of the bog the 08 450 hands down is one of the best 450 he's ever had! Never should have got rid of it but it had over 300 hours on it with two frames and multiple rebuilds but it never lost a transmission gear LOL!

There's just too much disrespect here now for riders and what's the point of divulging private conversations here so people can bash away?   A perfect example is back when people were ragging on Webb for being fat I got fed up and told everyone he has an issue with his thyroid.  The haters said this made no sense, yeah right, etc and I refrained from responding.  But then about 6 months later Webb covered this in an interview and explained the thyroid complications he had been dealing with.

For those who get opportunities to hang out and shoot the shit with these guys in a private setting where they feel comfortable to talk openly, it's not going to do them any good to come here and divulge information on Vital.  I would ruin it for myself and I would ruin it for others as they would eventually just stop talking freely.  I've had conversations with other top riders recently that would melt the Vital servers if I was one to disrespect them and spilled the beans.  Not going to happen.

Within the last 5 years, I've gotten to ride a bone stock, very low hour (10hr-15hr) '06 Crf450 at Millville a couple times. Those things are great. Still competitive in the chassis/suspension/motor department. The biggest difference is the way the engine spools up. There isn't an impressive/massive hit due to precise air/fuel mixture. Two words to describe it would be "lethargic" and "archaic"  which probably isn't a surprise with the understanding of EFI vs. carb. Past that portion of the power delivery sequence, the engine is still great and powerful. A 450 is too much for 99% of us anyways. Not even the older technology can mask that fact. 

Regardless, riding that bike was still a blast, and can be competitive in the faster classes with the right pilot.

I never said it was a secret, that's why I suggested to ask RC as he would tell you.  I just prefer not to divulge any part of any conversation that could be perceived in a certain way that the rider may not want out there.  If it has been published then it shouldn't be too hard to find.  I wouldn't know because I don't listen to podcasts and I don't read moto articles.  

The point of my post was related to the thread topic of comparing old bikes to new bikes, and I thought some here who still like and respect the GOAT, might like to know his opinion on the matter being discussed in this thread.  He got to race the old bikes, he still rips on all the current bikes, he's the GOAT, and he told me he feels the only game changer has been EFI.

The 07' and 08' were awesome and that was at my peak riding and racing ability. I felt so confident on my 07'. 

I just listened to a clip of Lars Lindstrom saying that Yamaha copied the 1996 Honda exactly. That the early 00s bikes that Reed was riding for example was a 96 Honda almost exactly.

All the different takes on the 05-08 CRF450R generation are interesting.

In my quest to see how much better modern bikes are than my 07 and 08 CRF450Rs (sold 07 recently), in the past year I've owned a 2008 CRF450R (with A-kit), 16 YZ250F (A-kit), 20 YZ450F (A-kit), 22 KTM 350 SX-F (KYB conversion), and 22 KTM 450 SX-F (KYB conversion). 

Guess what? The 2008 CRF450R is still my favorite...

Why?
(1) Handling is accurate, versatile, and forgiving
(2) The engine is a torque monster ("I'm a lugger, not a revver") that lays down thick and easy-to-use power - it's "chuggy!"
(3) The ergos were and are the gold standard
(4) The bike quality was excellent
(5) The reliability was outstanding

I will say that ALL of the bikes above I listed have incredible attributes to them - which is the reason I bought them to try in the first place - but none of them put it all together like the 2008 Honda CRF450R for me (FWIW - 2006 Honda CRF450R = too fast for me, 2007 CRF450R = best overall when I rode more desert, but I like the 2008 CRF450R for its more stall-proof motor with unique mapping for lower gears + slightly detuned state + 22-mm offset clamps since I ride tighter stuff these days.

Sort of a fun fact about Honda around this time is in 2005 Honda and Montesa made a fuel injected trials bike using most of the 250f motor, head and gearing and quite a few things I'm sure were different. 

My dad had one and it worked flawlessly, always thought it was pretty wild how early they figured out fuel injection before it was really commonplace in the dirt world which was probably closer to 2010 with the KTM owned Husabergs.

Hurts to say but i also liked the bikes from those years 06 07 08 ect better than my newer ones. Had a chance about 7 years ago to get my 06 back from a police impound and i turned it down. I sold it years ago and the guy never transfered the title. I guess he sold it and it was being street ridden. The police called me accusing me of street riding and running from them. I told them i sold it years ago. They were still being pretty shitty with me and said i could get it for impound fees which wernt much but i didn't want to deal with them and figured it was clapped. Now i wish i had another.
