Hi guys, i'm looking for some help with this bike, every review says that the new rmz sucks and it's very behind from the rest in terms of speed (also suspension)

Still it is very affordable, and finally it seems that I have the chance with one of these, but I don't want to fall behind the field so much in terms of speed, I have a fair good enough level for 250's so i'm affraid that it's speed difference is to big, so I came here for some recomendations on how can I give this bike some extra power to be in a near pace next to other japanese, I was thinking a good maping and an exhaust may be, but I can't think of any other thing to help with it. Or if mapping/exhaust can make the difference.

Please any advice from anyone who knows this bike and can cuide on how to empower ir? Any help is very usefull.

Sell it and buy a stock Yamaha rather than spend a thousand in the hope that it catches up 🤷‍♂️

Unless you're racing A class shit your suzuki is ok.
I'd recommend you to don't buy a zook, spend 6k and after 1/2k to get it working properly is not very smart.
You better buy a kawi/yami/ktm, spend 7/8k and be ready to race.

Long story short, I have this chance of a bargain where I can have a little money left to invest on the bike, for other japanese bike I would need to save more to buy. Also you are right, i'm not close to an A class pilot... Still if there are minor things that could make this bike more updated like the others, I would really appreciate it

Find 4.1 with a arc clutch and vp 4.1 fuel. If you really want to go for it remapped or get a vortex. Done.

Blunt Truth coming at you:

Are you fast? If not it’s probably fine stock.

Unless you are riding deep sand the bike is fine. I have a 2019 RMZ250 I just got a few months ago. It does seem to run out on the top end a bit quicker than other 250f’s I’ve ridden. But for what it lacks there it makes up for it with cornering and bottom end torque. If you are pretty light it will be more than enough. Just shift! 😆

Like others have said, buying that bike and then planning in advance to put money into it, isnt a smart investment. Keep in mind that the resale of the Suzuki will reflect that also. But if you insist on going in that direction, I'm not sure motor need a ton of attention. Peak hp should still be plenty. I think the main difference with some of the other bikes is the RMZ has more of the engine-brake, chug feeling. And strictly bolt-on mods aren't going to change the power curve / characteristics too much. If you have the cash, then mapping and exhaust is probably the easiest way to go. I was going to say that the suspension would be my first area of focusing. Some people seem that its good but others need it done up to be comfortable. I personally think going that route is also going to help you more than motor mods, aside from basic bolt ons. Unless you buy a Yamaha, which the suspension is already perfect for like 90% of people.

At your level, throw on an exhaust, get the suspension setup and run it. The magazines over exaggerate, the rmz is a plenty capable bike for amateurs even in stock classes at lorettas. Yes the rmz is quite a few hp off on peak power but so is the Yamaha ! Like the yzf the rmz makes up for it with low to mid range torque that the rest of the class doesn’t have

The bike is perfectly fine with exhaust and suspension. If you have a good deal lined up, do it and enjoy the heck out of it. Its a very capable bike regardless of what people who have never ridden one say. Signed, someone who had one

Check out HP Race Development vids on youtube. Guy has his own dyno and takes an rmz250 and does a lot of back to back testing with parts and compares it to actual dyno runs from the other brands he has had on his dyno. Same dyno, same guy interpreting data, same computer program, no third party input. Results are pretty interesting.

You don’t need to, get your suspension done. Save your money for oil, filters, tires, maintenance, when parts break and practice. Maybe do the air box mod.

Steve roman has no problems on a Suzuki. I don’t think you will either.

Dudes who run 10 miles a day, eat breakfast at 5:30AM, and turn laptimes ten seconds faster than most riders can tell the difference. If you are one of those guys, by all means mod the bike. Otherwise, enjoy it and be 99.99999902121999% as fast on it as you would on any other brand.

Braaapin' aint easy.

Suspension setting is an investment by default for me, doesn´t matter the brand. Thanks a lot for the comment from someone who had it!

I have a friend that purchaseD one, he loves it. Opened it up with a new high flow air filter (no screen) and slip on FMF exhaust. More air in/more air out. Made all the difference. The biggest change came with the filter change.

Throw blue plastic on it and it might feel empowered.

Somebody somewhere will still smoke you on a 125, no matter how much power you make. If you are extra lucky a kid on a supermini will blow your doors off in a straight.

Doesn't Bruno have that thing worked over pretty heavy? The thing sounds like an absolute monster. I'm not sure that bike is anything like what the OP is looking to do lol.

Trust me, the thing has plenty of power for you. You will never use it all. At your level the condition of the bike is more important than the bike you are on. If it fits your budget it's the right bike for you. If you listen to the ninnies here you will never be happy. Get the bike, they are great motorcycles and you will be very happy with it..

I bought one 2 weeks ago and I love the bike.I put a fmf 4.1 slip-on and I revalved the suspension and now the bike is perfect.I had a yz250f and yes the power was a litle bit better but the rmz handle a way better

go to https://www.keeferinctesting.com/motocross-testing/2020/8/9/2020-suzuki-rm-z-250-blue-collar-project

cheapest mods:

cut the airbox down (its apparently bottled up pretty good)

add a muffler

better air filter


and if you have money do these also

head mods

vortex ecu mapping

Send the motor to Varner.

Rmz's are great. I haven't found anything that's negative and frequently said about the newest generation rmz's to be true. Buy it, you won't regret it unless it's beat, beat.

Hi I’m just starting MX bought the 2020 rmz 250 about 25hours zero problems! The only thing I did per advice from Michael Keating who races Vet expert! Who posts here under the 250rmz was change springs to
4.2 at my weight of 145 and looking to add a Yoshimura pipe but I’m not using all the power !! Had a friend who races a 450rmz help set up sag etc He is a ex pro who races and wins vet experts consistently! ...Great Bikes if you’re on a budget! My thoughts learn on this move up to a Husky 🤠
