When to buy a 450?

My son is about to turn 18. Been on the 250F for almost 3 years. He is still a C rider, had over a years worth of down time due to injuries. However he rides a lot, we have a nice track here at home so I spend a lot on just up keep on the 250's. He has recently stopped riding as much and his stamina has suffered, so wants to get back to riding more so this kinda leads into my question.

He had a very nice gentleman offer to let him ride his new KTM 450SFX this weekend. He only did 3 laps. I told him to go out and just be easy. He listened for 1 lap, I saw him rip out of turn and I could tell he liked it. He proceeded to rip off 2 laps as fast or faster than his YZ250F hitting all the big jumps like he had rode it for weeks. He loved it.... I have a 08 CRF450 that he rides great, but he laughed at it later and said it didn't compare to that new KTM lol! He has always rode my 450 well...


He can ride and handle the bigger bike but I have had many friends advise me against buying him a 450, as he is still relatively young, as race/seat time goes.

I intend to keep our YZ250F's for him to race this year and possibly next at AMA events. However I am really considering buying a 450 for him to practice on maybe some local races. Gonna make one of the 250's an AX bike...

If we do get a 450 he wants to ride the Honda, and maybe if the new Yamaha get here soon try that too.... Right now he is all about that KTM....

I am looking serious opinions from experienced riders, trainers, parents, no jokes please....

I was 19 when i got my first 450. A 450 fits me better than a 250 or a 350 since i like to ride with lower rpms.

If he feels like he can ride a 450 without feeling like a passenger on the bike, go for it! It's also way cheaper to maintain a 450 compared to a 250 so it will probably save you some money.

You know my son is 19 and he also likes/ has raced / rode my 450s in the past. He is an intermediate pace but doesn't get to ride much since graduating college and now working full time. We have talked recently about getting a 450 but in the end we decided the 250 is best for now because he really enjoys it and the 450 is alot of bike even if you are in good shape. My opinion is to keep him on the 250....

is your son a big kid?

personal opinion, i think 450's are great for some people and terrible for others.. if your kid is strong enough and is smart enough to ride within his abilities, i dont see a problem with a 450..

but if hes a little guy that needs more strength i wouldnt put him on a 450, that could turn into a disaster or a really steep learning curve

Imo he is fine in the 450 as long has he understands to respect it.

Some are more forgiving than others though!

I'd say keep him on a 250F. Just keep a stock 250F as a practice bike and they should hold up pretty well, especially with your son trying to get back into it. When I quit racing at 19 as a decent B rider, I was right around your sons size and would ride my dad's 450 every once in a while. The 450s make everything easier to do and it seemed easy to actually get in more trouble when I went back to my 250 since I would get use to lugging the 450 and not having to really carry any momentum.

Maybe the best thing to do is look into a 350 if he liked the KTM so much though since they do need to be ridden more like a 250F so he won't lose that aggression while having a more reliable motor.

If you can afford multiple bikes, buy a bunch! You can always Stoke a friend! As long as your kid is big and smart enough, no problem.

If he likes it and rides it well then why not?

What is his ambition? Just to be a local fast guy/ local pro?

I agree with TSCHAM. If he's just wanting to stay local and enjoys the 450 more and is faster, I wouldn't shy away. But that's a lot of power so he just needs to learn the abilities and not ride outside of them.

Local C, or national level C? Had my son race local B on a yz250 for a year before we moved up to a 450 at 17. If you think he can handle the bike, why not go with the 450?

Dating myself here, but I moved from 125 to 250 when I was about 19. If he is an experienced racer, it shouldn't present a problem. I'm assuming he's already doing most if not all of the doubles/tables at your local track. If you are buying him the 450 to make the jumps easier, then I would say don't do it. It will only lead to injury.

I like your idea of keeping the 250 as well as buying the 450, that's really the ticket. Learning to ride the different displacements develops you as a rider - with the slower bike, you have to focus more on momentum which is great for your corner speed on the big bike. With the faster and heavier bike, you get stronger and feel much more aggressive when you switch back to the smaller displacement. It ain't cheap, but if you make sure he is getting seat time on both, I think it will pay off in making him a better/faster rider all around!

I raced a CR480 at 16. He would be fine. But...I'd recommend he get fast on the 250 first. It takes skill to go fast on a less HP bike. Those skills will translate well to a faster bike. If he's still riding C on a 250 he has not developed the skills. The other side of the coin is to simply go with what he enjoys. At the end of the day it's all about having fun.

450c is generally a more fair class than 250c.. Less drama with the do or die kids and less sandbagers. I would rather be on the 450 just because of this.

I hopped on a 450 at 13 and was still a C rider. I was maybe 5'8" and 135lbs. I simply liked it better than the 250. At the end of the day, that's what it boils down to. Let him ride whatever he enjoys (and can afford).

I waited until I was 47, but that was a little too long, I could have handled it by 45 easily......

I can't really tell you exactly what to do but I feel like I can relate to your son. I'm 21, 6'0" tall and about 195lbs. I'm not fat, just a big guy by nature. Ive ridden a 250f for about 5 years now (C class like your son) and every time someone has let me ride their 450 they tell me I look much more comfortable and fast than on my 250. The extra power just fits my body size and riding style better.

It really comes down to how he likes to ride. I do not like ridding at high rpm's. I like lugging and rolling through corners to carry momentum and then get into the mid range exiting corners. Railing on a 250f 3rd gear topped out just doesn't suit me at all. I generally run a gear higher than most people do on a 250f and carry my momentum more. So if your son is like that and has loved riding the 450's then I'd say get him one.

Two of my fiends just bought brand new 2017 hondas and I can already see them going faster than they were on their 250f's. Their body language says it all on the bike. I can't speak on the KTM450 but from what I've heard/read you're better off getting the factory editon of that bike. A lot of reviews compare the 2017 Honda 450 and Factory Editon KTM450 as the two best bikes this year.

Age and size has nothing to do with it.
An 60/80 Expert can get on a big bike and get used to it in a few minutes.
I had a big tall 250 at 11. Got on and off by riding up to a jump. I could touch the pegs. Ground not even with tip toes.

First time I rode it, I was clearing the triples I couldn't do on my minis.

The 350 is a great bike but you have to ride it exactly like a 250f. I actually think the last 250f I owned had better bottom end.

Wow, some wonderful insightful posts, I APPRECIATE IT! Thank you all very much....

He is a local C rider, and wants to be a local pro, A rider maybe try for LL's one year. No pro career dreams or anything...


He seems to do better at the lower RPM's, I have always tried to teach him not to ride the rev limiter. One reason he liked the YZF so much, is that bottom end power.

It is strange you guys mention the 350. I just hired a mechanic to work on some bikes, and our stuff, at one of my shops. If it works out we are going to fully open to the public. Anyway he is a KTM GNCC rider. He happen to trade for a 16 350 SFX with around 60 hours on it. He needs around 6k for it. I just have never been a fan of buying used 4 strokes, plus knowing it was a practice bike for a GNCC kid scares me...
