Testing Ken Roczen's 2023 Progressive Insurance/Ecstar Suzuki RM-Z450 

BEST reviewer for any dirt bike. Period. Thank you Michael

Kickstart Kenny has been RIPPIN on the RM! Love to see it

You sir do the best reviews by far. Much more in depth and descriptive than any other reviewers. Very engineer like with great rider feedback. You know how to give us the right info.

What did most people say ?? He won't do well on it blah blah Er I think he did 🤔

Michael, your insights on these are next level. Anyone not appreciating your knowledge is probably on Vital, arguing about fireworks.

Beautiful bike. RM Army!!!!!

Awesome you talked about them actually lowering the compression ratio to get better burn in the cylinder at high revs. That’s a hard thing to manage when these bikes are supposed to have useable power from 4-12000 rpm.

Very impressive facts about the triple clamp situation and fork choices.

Great review ML thanks

Photobomber! LOL! Saw you on the MXA video on KR's bike! When I saw you, I was looking forward to your review and it didn't disappoint! Thank you for the content ML512, BTW sweet kit!

Hey ML, what do you think ballpark would it cost a vet rider to build this exact bike including cost of a 2024 rm450? I have a feeling we are gonna see some roczen specials this year at the Perris vet track.

I wish for a new rm250 and a new rmz450 and a new rm465

Question: do the Factory teams, like Honda/Yamaha/KTM race the same bikes (frame,motor,suspension,brakes, etc) as production bikes that's sold to the public? Or are they a different bike in its entirety? I understand they have certain parts that aren't production parts, triple tree, hubs, electronics/mapping, etc. Do they use the same suspension as stock but with engineered/after market internals? Do they change the motor internals or are they modified stock parts as sold to the public? How much $$ is a Factory bike cost? Are the "works edition" bikes even close to factory bikes?

if your a racer, why would you not choose Kenny's factory bike over a new stock production bike?

Of all magazines,this TECHNICAL BREAKDOWN was the best. Better then Keefer's .

Love how you dig deeper into the specs than anyone! You’re definitely the best at reporting on factory equipment by far. 👏 People have said you could buy the majority of this bike and I bet there are a few vet guys that would buy most of the stuff if we knew where to get it. Any chance you can post links on where to get identical stuff that’s available to the public??? That’d be greatly appreciated if so! Shoot…earn a commission on it if you can. 🤙

He'll I just watch some other people just ride his bike..lol😊 every one gets to ride Kenny's bike today

The restart problem would kill me as a pro that's why I like the good old best of all time dirt bike and quads are 2 strokes we all know it takes more skill to a 2t fast on track but thats why i like kens bike cuz his is a kicker gotta give it to him for being a real man 🤣

Bruh your review is so good

Incredible insight! Thank you!!

Omg!! He is so lucky. I wish I could test that bike.

Very indepth review, good stuff🏁🤙

I want a slipper clutch… why don’t people make them? Always hated 450 engine braking.

Nice

Interesting that Ken chose the 250 triple clamps because they are further down but more likely because he spent so much time on the Suzuki 250 he’s probably very comfortable like that.

the stock 450 good with the 250 rear shock that what you never mention Kenny ran that 250 shock and stock spring it looks like
