Comparing yfz450 to the 450R

Just Like the subject says. Is there anyone that could give their opinions on the 2? Currently have an 08' pretty built. (Houser +2 a arms,durablue axle, Elka stage 3's all the way around, port/polished top end, exhaust, intake) you name it. How would you rate comparing the older yfz similar to my upgrades to the EFI in all aspects? Let's say with just an exhaust, intake, & tune. Worth the extra money? Wish I knew somebody with one nearby to try it out!

Wider from the factory, smoother power delivery....The carb quads you could stab the throttle hard and be left sitting in air....LOL....I think the R handles better.....Carb bike cheaper to mod....The R's need a Vortex....

R for days. Unless you refuse EFI, carb models don't compete with R's.

Funny you mention this though... there's a guy selling a 2012 carb model motor, AArms, swingarm, shocks and a seat on a local Facebook page, but he's claiming them as YFZR parts. I called him out on it nicely, and it's only gone downhill. Him and a "mechanic" are telling me that the injector is right there and I don't know what I'm talking about. There is no carb or throttle body in ANY of the pictures. The motor has the external oil reservoir, starter in the back, starter gear bulging out the side. The front shocks don't have reservoirs on them, and the rear doesn't have the adjusters like R rears do. The AArms are the short curved carb model arms. And not to mention the seat doesn't have wings like R's do. "The title says YFZR, so that's what it is". You know, standard Facebook dorks. I'm having fun with it now. Lol.

LOL!!! Wow, and don't forget the kind of guys that are selling their 04' with a slip on exhaust on Craigslist for 5k... anyway, yea I'm always curious about upgrading to the R but would wonder how much of a difference there would be compared to one like mine that's pretty decked out.

In all honesty, it's a huge difference. After I bought my R, I was gonna keep my 07 Carb and use that as a backup... there is no comparison between the two. So I eventually traded that for a 06 RMZ250, which I traded a few months later for a 09 YFZR. Lol.

The R is better for taller riders.

I sent a link a while ago. Not sure if you can see it since it's a closed group. If you can't I'll take screenshots and post them. Lol

Where it really matters to me besides the EFI and Carb, are the measurement of these bikes. I race against a 14R with my 08 Carb and his handles a little better in the corners, which is notable in the videos I've been taking. But I've only been on my yfz for 3 race now and he's been on his for a year before. Things might even put here a little bit. The mods between our bikes are almost identical, where as he has a full gytr system, vortex, port work, and gytr high compression, carb cam. I'm sitting on a slip on, full intake, 14:1 compression, Dasa port job, stock cams. We got a chance to brag race last Saturday twice. When we crossed the line it was so close every time that we couldn't tell who won if it wasn't for the light. Gonna mod my cam this weekend to suck a little more power out of the bike now and match my bike width to his to see if it helps with my tight corner handling.
Carbs have made more power back in the day, not real sure about that anymore though.
On a note when we raced I won once he won once, it was all won on the light.

Length x Width x H
08 Carb Model - 72.4x46.1x42.9
14R Model - 70.7x48.8x41.9

Oh cool, yea that was more of a comparison that I was looking for. So have you hopped on his R and rode it? If so, how did you like it?
