Dt170 vs ktm exc 125

[DTR+NSR]

I doubt the crm has a genuine 30bhp. I've got a nsr125 with basically the same engine as the crm. Doesn't 'feel' that much faster than my dtr, wether that's just down to the gearing, as the nsr has alot longer legs.

@declan Yeah right, KDX's were poo! I think that number has been massaged slightly. But you know, not impossible figure.

[declan]

@calum what year you on about mate it seems the old 89 ish were 36 then the “newer” ones around 26

[Calum]

@declan Old 89 ones being 36. Definitely not then lol.

I dunno, I could be talking absolute brown. I've been on a 1991 KDX125 and it wasn't exactly savage. And they reckon they are 24bhp. Which again I doubt.

But as said, long time ago and I have no reference any more.

@calum but you believe a crm is 30 bhp and a Yamaha dt 20 bhp? How is that difference even possible?

[declan]

@irongamer727 well you gotta understand that bikes aren’t always in competition with each other it’s just the way it is for example a ktm 525 I thought would be a beast but it’s no where near as fast as any 450 not that I’ve ridden either bikes

[Calum]

@irongamer727 No, I never said the CRM was 30 lol

Pretty sure no one did.

[Irongamer727]

@declan huh? A Ktm 530 is most definitely faster than a Ktm 450. More torque and more power and basically the same weight.

[Irongamer727]

@calum The fact you did not correct me made me wonder

[Calum]

@irongamer727 I won't lie, I thought you were Trolling lmao

[declan]

@calum what’s preventing my am6 engine from reaching say cr80 performance say I put a cr80 head on there magicaly get the crank to fit with the carb etc would it essentially be nearly as fast as one like what’s the limiting factors apart from fitment of Honda parts

[Calum]

@declan Cylinder wall thickness I expect. Only so much porting you can do.

You could get the DT to be like a YZ. Just needs blue printing.

[declan]

@calum so I can get performance cranks which increase compression there’s a few so your saying that with a nice crank re bore and specialist porting I could get pretty impressive figures? I’m obviously and a Bafoon when it comes to this stuff

[Irongamer727]

@declan the am6 has so much tuning potential. You could go for the Parmakit 110cc or for more performance the Stage 6 90cc or something like that. But spending those kind of money on a moped engine isn't worth it. You're dt is still going to run better.

[declan]

@irongamer727 yeah those kits are mad expensive In some cases I can get Airsal kits for around 200 Ish rated for around 14hp maybe if I paired that up with a nice crank it would be nice but it adds up I guess

[Irongamer727]

@calum listen to this. https://youtu.be/IuAemxWYHLw It is sounding sooooo good. Especially on idle. Love that 2 stroke sound. But, my Dt never sounds like that. With arrow exhaust. Do you need like a fmf shorty to acquire that type of sound?

[Calum]

@declan I'm saying with lots of cash you could achieve anything. But it's pointless at this point as you may as well have bought a better engine.

[declan]

@calum like a dt engine

[Calum]

@declan Like a Rotax engine. Personally.

I think they're really versatile. Loads of tuning bikes, were used competitively yet have all the features to make them tame for the road. Can be tuned very well, and take lots of power.

[NINJA]

@calum Take or Make lots of power ???
