Why do companies keep pushing single cylinder engines?

[Jason Voorhees]

400+ cc single-cylinder bikes often struggle with reliability and smooth performance. Many of them face issues like incomplete torque bands, excessive vibrations, poor mileage, and stalling. The larger displacement combined with a 4-valve setup doesn't seem to make sense. Wouldn't it be better to cap it at 250cc or move to a twin 300/400cc setup?


A practical comparison would be the Ninja 300 vs. KTM RC390, where the twin-cylinder design clearly outshines the single. And this isn't even about power-to-displacement ratios—it's purely about refinement and reliability. So why do companies keep pushing single-cylinder engines in this range despite these recurring issues? The only argument I can think of is that using a counter balancer rod is easier in a single cylinder than a a multi and it being easier to maintain. That's about it. Any mechanical engineers or fellow bike enthusiasts can explain this to me?

Can't help u bhai, I'm studying bio in hopes of becoming a doctor to perform surgery on myself.

Oh yea for sure. Insane power-to-weight ratio and violent torque delivery. Literally feel like riding the dragon.

Why's that? I've been driving motorcycles since I was 15. Literally drove them in the main city without any gear or driving license.

High inhib parents honestly I dont like that kind of parenting at all. Sheltering your kids from life experiences at some point arr going to have to learn how to ride a bike.

It is always a jew

When i first found about the jewish theory I found it to be absurd how such a small group can have so much influence. I even denied at first but as I read more into these things every issue in the world seems to somehow trace back to the jew, its always somehow, for some reason always a jew...

I don't say it out loud, like "jew"

It's not like "jo"

It's with a snare, and a distasteful snicker, an h in the middle that drags the word out and makes it even more sinister

Does Tomos still exist?

They dont make mopeds anymore but I think they make fatbikes jfl

I haven’t chosen what type of engineering yet

I was thinking mechanical but it seems hard and too much work on a computer for me

I think I’m gonna just do civil instead

Nigger ur gonna save up money in 13 days

Next 28th won't hit like this one

I'm unrionically gonna make all my OLD accounts and post on insta finally on that day

And told some niggas I know irl to make moves

Computer science is fun, I have a class for that in my program, it’s really easy stuff tho it probably gets fucked

 

[StarvedEpi]

@StarvedEpi has a ninja 300 if my memory serves me correctly

i got a 400 the 300 are the previous gen

 

[Deleted member 87612]

to save costs. also despite the benefits there is still a shit ton of demand for lower cc engines, especially by the youth

 

[User28823]

cause ppl will still buy it
