Uncorked and Capable 2017 Suzuki RMX450Z with Yoshimura RS-4 Slip-on and JD Jetting Tuner

[@trevorjameson3213]

This is THE BEST video I've see yet of riding an RMX450! Great riding, awesome hills and trails, and the bike sounds perfect! I'm getting one of these bikes very soon and can't wait to get it dialed in, uncorked, and go riding!

[@denniss5845]

Totally agree with you I just pick mine up yesterday it's still in the breaking process can't wait to unchoke it I'm going to wait after 600 miles I don't know why but that's my magic number

[@denniss5845]

@Sinister Veritas that's good to hear I'm at 40 miles when I hit 100mi ill take out throttle stop and shortly after fully unchoked with the removal of the P-trap in the exhaust enjoy the ride have fun

[@dereckrodriguez9688]

@@denniss5845 what I mean is service wise. Most dirt bikes go by hours. I was just wondering if interval wise these are hourly or mileage. Also how many miles do you have on it now?

[@Dashriprock4]

That bike sounds like it is running spot on!

[@adiofreack]

i have a 17 rmx450z also, and i got mine plated with the tuner, bigger front sprocket and supermoto tires and it hits 110 on the highway no problem and rides smooth and reliable! best purchase ive ever made.

[@yourmomsfavoritemutt887]

Circa hello so to bother by any chance did you take off the throttle stop screw ?

[@821ogw2]

What's Best for trail? Stock or bigger front sprocket? i got 48t rear on my 2017 450 rmz

[@kgbr1978]

I have a 2010 rmx model. Purchased and owned since 2010. Snorkel removed. Yosh cherry bomb. Best mod for this bike is a magura hydraulic clutch. Take the 15 minutes to install it and you will be glad you did. Aside from normal where tear items mine is all stock. Regular oil and air filter changes. Complete oil changes. (Filter and *both* strainers) my bike has 7800kms on it and have not had to adjust a valve. Leak down test completed and still almost 95%. Amazing all around bike. Motocross track occasionally but mainly tight single track.

[@stmboat]

How tight? Where are you located? I am interested in this bike and its ilk, but cannot determine its ability to resist stall/flameout at low rpm compared to 2stroke.

[@TEKKYTWO]

fantastic video bro I really like the rmx 450 great bike

[@NOTTApro142]

Man I am interested in buying one of these and I thought there was only kickstart! Now that I know its got E start i totally want one!!

[@denniss5845]

Great with video I just pick mines up yesterday please make more I'm still in the break in process after that shortly I'm going to unchoke mine also and making it street legal with tusk street legal kit

[@markalan4026]

Nice bike!

[@quebecbroil]

i want one badly, i sold my yz450 2015 because i was doin less motocross and the yz was not a great trail bike, but i wonder if the rmx suspention is ok to go on the mx track occasionally

[@stupidmoto]

Definetly NOT ok to go to the mx track lol. I'm a lightweight and I still bottom out the forks on small jumps all the time. If they where re-sprung and re-valved to resist bottoming out it would be great. Besides that it's an incredible bike all the way around. I'll be making a video soon going into detail about owning the bike

[@quebecbroil]

ho, thanks for the fast response, can't wait to see your next video

[@JaredValentino13]

It’ll be fine on the track

[@MrNismopro]

That’s awesome. I pulled my limiter screw and the intake baffle. I’m ordering my RS4 full next week along with the JD tuner. Does the bike need to be tuned? Or, does the JD self adjust the right mapping?

[@Michigangminibikes]

What are those handguards?

[@ItzMurphhh]

Seems like it runs way better! Tell tracy to put air in his front tire lmao

[@piedrudopiedro8151]

Awesome bike, JD Jetting Tuner works on 2016 model ????? thank's..

[@bryanlefebvre8815]

What are your settings your running on the tuner? I have same bike with similar setup but wouldn't call it a ripper.

[@Gtdubsterx7]

Hey moto I have been having some issues with my rmx stalling and not like starting. Is the jd Jeter a good option? Is it hard to tune or set up? My bike just has all the EPA crap taken out and am thinking of trying the jd. Any advice?

[@Gtdubsterx7]

Sorry it also from the rs4 slip on vid where I had the low to high idle sounded like it might be the exhaust since it didn't do it with the rs4 but when you put the stock one on it did

[@desertdrz]

Do you miss the drz? Looking at next bikes, either yz250fx, wr250f or this. Wr450f is $600 more than the rmx450z so that's out.

[@stupidmoto]

I still have my DRZ but I don't miss riding it, the RMX is a completely different monster

[@mikeayala8394]

I just Bought the 2017 RMX450Z and want to change the exhaust system but was told I need a tuner... how do I go about this

[@stupidmoto]

get this www.jdjetting.com/xcart5/jdsx04-suzuki-rmx450z-17-efi.html it installs very easily and is fully adjustable

[@xDivBlitz]

Hey ive just brought a JD tuner i have it installed but i dont know how to tune the bike, its got a full yoshi system, any advice on what to do. thanks

[@stupidmoto]

ok so the tuner has different "zones" that correspond to different RPM ranges on the bike, and each zone is color coded. to adjust it use the mode button to select the zone you wanna adjust, then just use the + or - buttons to add or subtract fuel. adjust it to where you might hear some deceleration popping sounds ever now and again from the exhaust. these bike run super lean from the factor, so if you richen it up too much you run the risk of the bike running too cool and you might get gas in the oil from the piston rings not getting hot enough to expend and seal properly, which is what happened to me, but all I did to fix it was lean the bike out more.

[@xDivBlitz]

Thanks alot appreciate it

[@xDivBlitz]

So i have had a go with it, when i give the bike a rev on the deceleration the bike is shooting flames, does that mean i need to richen or lean it out? thanks

[@stupidmoto]

you need to richen it up

[@suzuki06g]

The JD Tuner is just a rebranded Power Commander V without a preloaded map, that's why it's cheaper. If you had purchased a Power Commander V then you could have downloaded one of their dyno tuned maps that were already run on different configurations. Just pick what matches up the best with your current bike setup - like say you have the exhaust baffle and air box snorkel removed, they have a dyno tuned map for that. Just install it and enjoy your new found power. This is one area where JD really comes up short, I love their jet kits but their tuner needs work.

[@SadHippieMane]

What is the maintenance schedule? Would really appreciate a reply !

[@stupidmoto]

first service interval is at first 100 miles, which includes oil change, cleaning oil strainers, and you're supposed to check the valves too. after that its oil changes every 600 miles, and valves aver 1200 miles. I have just under 500 miles on the bike and I've had it for 6 mounts. I've heard people say they are as durable as DRZ's, so if thats the case, this bike will run forever lol

[@plecours1]

Do you have to reset the tuner every time you turn off your bike ?

[@stupidmoto]

No it stays where it was last set

[@plecours1]

@@stupidmoto ok my tuner was not saving my setting turn out to be a Ground issues .. is it a rmz slip on you got There ?

[@stupidmoto]

@@plecours1 yes its an RS-4 slip on for an RM-Z, the mid pipe was too small for the RMX header so I need to make it bigger with a tubing expander and an impact gun. I'd recommend getting a full system or slip-on from FMF if you want to avoid any issues

[@johnnyu9692]

yo which hand guards are you running?

They're the Enduro Engineering wrap around hand guards

[@Bt26x]

She looks & sounds good man! I have always wanted an RMX450z every since they came out. I was so pumped when they came back out last year, but then after reading about them I was a bit on the fence. They said you can't do much to them & the ECU was locked. But now I see that you have a tuner on yours & you say it rips. That gives me hope! I remember the reviews in 2010 they were saying it was basically a full blown race bike w/ some off-road parts on it & now their talking about it like its a crf450x. I'm just wondering if you can get it back to being really race capable like it once was. do you know if you can you put a RMZ450 ECU, airbox & exhaust on it? Did the JD Tuner & Yoshi make it a whole new bike? Awesome bike man, I'm jealous. I'm about ready to sell my 350 & get one! I'm curious if it'll get the 2018 RMZ450 update in the next year or 2...

[@stupidmoto]

the only difference between my 2017 and the 2010 is the ECU, they are almost exactly the same bike believe it or not lol. so yes it is race capable. not sure about the rmz air box, because the whole subframe is different and the plastics are different. im almost positive the rmz ECU won't work because all of the extra wiring and electrical things like headlight, speedometer and electric start. the tuner and slip-on makes it a new bike. it feels just like an rmz woods racebike. its the best bike I've ever ridden by far. I would wait till they announce the 2018 rmx450z to get one, it could be on the "new" rmz platform, but it still might be the same bike as 2017. even if it was on the new platform it doesn't look like they made any big changes. either way the 2017 is a ridiculous bike with $600 in mods done to it.

[@Bt26x]

stupidmoto thanks man!! Good info. I'm fine with how the bike looks even if they don't change it. I have always love that bike because I've always been a big Zuke fan growing up. I saw in Australia they make a dual sport version of this bike, which is what I would do w/ mine here (Georgia). I like having a tag on it so I can ride all the forestry roads up in the mountains and cut across the back roads.

[@alexgroezinger762]

What’s the mpg on it I want to know

[@stupidmoto]

ya know thats a great question, I'll find out and let you know once I run a full tank through it

[@stupidmoto]

Ok so I got 35 miles of aggressive trail riding before the fuel light came on

[@alexgroezinger762]

stupidmoto cool thanks

[@cleanmachineautodetailing]

Street legal?

[@Cgny]

You ever rip down the road on it at all? Wondering how the gear ratio is. Considering getting one and plating it

[@Cgny]

Lol. Guess I didnt get far enough into vid before asking lol

[@stupidmoto]

lmao the gear ratio is great for the road, I've had it to 90 mph pretty easily when it was bone stock, not sure what it does with the mods on it. I also plan on plating it, but I have to either pay it off, or somehow get the financial company to switch the title to street legal.

[@Cgny]

I got my 13 WR450F plated through South Dakota by filling out some forms and mailing them in. Im from NY. I had a loan on it. Got the plate and regi through them but the State/DMV hangs on to title until its paid off. But still allowed me to ride legally on the road and was a pretty easy process.

[@dillonperron6536]

If you were to take it on road I'd suggest an increase of gear on the front sprocket to give it more top end speed

[@ryanlangelan2135]

Did you use default JD settings? Or did you have to adjust? If adjusted, can you post them? Thanks!

[@stupidmoto]

no I am not using the stock settings. all of my settings are 5 or 6 or in between, except the accelerator pump which I have at 4 (the ap setting is kind of personal preference). I had to actually richen it up slightly setting everything around 6 to make it run better in the hot weather, which only takes about 30 seconds to change

[@ccheeky8459]

what mods has it got

[@stupidmoto]

just the RS-4 slip-on and the JD Jetting EFI tuner

[@ccheeky8459]

ty

[@cooperlindeman8039]

Bro you outta put an ims fuel tank on that bime

[@stupidmoto]

I might if I do some harescramble races this year. I usually only ride about 20 or 30 miles at a time, and I get about 40 miles out of the stock tank so I haven't really needed a bigger tank yet, but if I do some races I will definitely need a bigger tank.

[@redpepper007]

don't speed up the video mate, looks horrible. Your'e going 55 but it looks like 150
