First Ride 2021 Kawasaki KX450 - Motocross Action Magazine

#motocross #kawasaki #supercross #racing
Motocross Action Magazine tests the 2021 Kawasaki KX450 out at Glen Helen Raceway. For the 2021 model year Kawasaki has mad some subtle changes to the motorcycle including a larger diameter clutch, new handlebars, and a new coating on the piston. Will these refinements be enough to win in the 2021 450 motocross shootout? Only time will tell and we have a lot more testing to do before we get there. Sit down and relax as Assistant Editor Josh Mosiman walks you through the new Kawasaki KX450. Don't forget to like,subscribe, and share our videos! Thanks for tuning in!

My son races the 2020 KX 250. The bike is very good, with great handling. At the 30 hour mark, we broke a valve spring... a piece of it snapped in the cam chain causing 1 chain plate to bent. This in return ate in the plastic chain slides. The scraped off plastic collected in the oil pump resulting in oil blockage to the big end... engine was broken. This was a big bummer and not what I expect from a premium Japanese manufacturer. I have raced several KX 125’s and 250’s myself back in the day, I am a Kawasaki guy. But I hope the durability of the 21’s will be better, especially on the high rpm 250’s. I really like MXA’s tests, been reading since the early 90’s. My suggestion is to do a review test after 1 season.

Kawi has come a long way. And the reason Kawasaki didn't upgrade their 2020 450 lineup is cause they spent most of their budget on the 2020 kx 250f.

[@skylarkumm9450]

They sure did. Just bought one and i’m overly impressed with it.

[@Alex-dv6ro]

I ride the 450 kx 2020 stock as I like my bike to be stock. Only have xtrig triple clamp with a scar racing bar. The only issue I had so far is the throttle system. It's the third time the thing is stuck I mean doesn't come back so I'm changing the whole system this week with way better quality. Otherwise the bike handles like a dream. And it's not known so much but this bike come with a very special fork, it's not the standard showa like on the Honda the fork cost actually more than half of the bike if you want to buy it alone. Good job mxa

Ive been on it (and my '96 CR500) for 14 years. Granted, bikes have come a long way, especially with the stock suspension, but a good rider, reworked suspension and proper setup will embarass these $12k ticking time bombs.

Today riding my 450 kx 2020 I was thinking. All this video from us magazine they say the fork is too soft. I find it way to stiff I mean even landing properly is very harsh feeling. Or we don't have the same setting for Europe or there is a huge difference at a pro speed. I don't know I had my bike mid may I am taking the 2021 and as soon as I have it'll be straight to the suspension shop. Even the shock spring is so stiff I can't fix the rebound when you're a bit short you just rebound 3 meters after the jump...

Hey man, that was me riding the bike. Our goal at MXA is to breakdown each bike so our magazine, website and video readers/watchers can be informed on what's new, what's good and what isn't good about the latest bikes. Manufacturers give us bikes and we give people feedback so they can make an educated decision about which bike they should buy next. If you want to watch a video of someone only talking about the good things about the bike, then there are plenty of other videos on youtube for that. The MXA reputation was built on telling people how it is and that's what I'm aiming to do. If I told you something was great, you bought it and it sucked, would you think I was a nice guy? Or would you feel like I misled you? I appreciate the feedback anyways even if we disagree
