Dt170 vs ktm exc 125

What? No. KTM EXC are enduros. It would be like comparing WR200 to a dt125.
The sx is a crosser, which the exc is practically the same jut different gearing.
The engines are measured in hours not miles. About 40 hours to a rebuild. They are the ultimate 125.

@calum I am aware that they are enduro bikes, I looked up the specs after I saw your comment and that they are all listed at 15Hp;
http://www.motorcyclespecs.co.za/model/ktm/ktm_125_exc 09.htm
So hence why I asked if the ones listed are restricted bikes at 15Hp and de-restricted aka full power bikes are the 33BHP you stated ???
-

Yeah, they are around the 35 BHP mark. They are totally savage.
So I would expect the DT would have more torque with the extra cc's.
But It won't matter once the EXC gets going it's just going to decimate the DT. It's everything, it's 20kg lighter, it's virtually got no flywheel. It's a full bred race bike so everything is just better spec.
Enjoy a comfortable ride pooting around on a reliable dt though.
It's not all about power.

@calum AAAHHH right race bike, a bit like the MX/RS Rotax engined bikes?
The lighter weight would make a big difference, but only if the riders body weights was evenly matched. I seem to remember reading somewhere that a full power DT was 28BHP, is that not correct ???
Wouldn't the extra torque give it more grunt aka pulling power at higher RPM's tho ???
-
@ninja The DT is no where near that. 15 BHP Stock. And as our dear friend from overseas found out, a highly strung Belgarda made 24-25bhp on the dyno quite recently.
The MX/RS engines...yes and no.
Yes, they are Rotax 122 Go Kart Engines. But they are detuned for the Road. But Aprilia sell GP kits to bolt on and make them full power. But they are far from it stock. Around the 26bhp mark from new.
-
@calum surely a destricted Dt with stock exhaust will have around 20 bhp. I think with the Athena and performance exhaust your looking at roughly 30 bhp.
-
@irongamer727 No, nowhere near 30 bhp.
Those Athena kits are poor. Two strokes work best with square engines. Throwing a big bore on it just makes it overly square, same thing with the old dt mx 125 175, practically same engine, bigger bores.
So what do you get. Well you lose over rev for starters. You lose the ability to obtain high peaky power. Instead you exchange that tor torque, as I already said, it will probably have more torque.
But it's not enough. In race engines, torque is only good on slow twisty tracks.
Once the engine is spun up, the inertia is going to help move it along. With the KTM, sure it'll lack low down grunt, but who races at 6k on a two stroke. No the engine will be maxxed out to 14k and will decimate the dt.
I'm not saying torque isn't important, as it most definitely is. The exc doesn't lack torque. But the extra torque gained from the Athena won't help it beat an EXC. You will just have to ride one to really understand.
-
exc will win without a doubt, the DT might be faster off the line with the extra torque but it is also much heavier, I can't honestly tell which would be faster. However it's only a matter of a few seconds before that top end power kicks in and pushes the exc well past the DT. An exc is a 2-stroke enduro bike, it has weight and power on its side. Anyone who's ever ridden a 125 enduro bike should know the exc will kick the DTs arse.
-
Im pretty sure the excs are restricted for emmissions, I belive the dealer adds another exhaust at purchase.
-
@jens-eskildsen Again, it's an Enduro, they are not made for road use. So why woud they be restricted for emmisions. You may be riht. But I don't think they are.

@terry-tz said in Dt170 vs ktm exc 125:
with a 170 kit on it could you not put a smaller sprocket on it for more top end then it would match the exc I mean I feel that it would be a waste but the 170 is a waste, to begin with in my opinion
A DTR with 170 Athena kit is no match for a 125EXC from a standing start the KTM will be in 3rd gear and away before the DT is even moving. I remember years ago my mate had an RE with one and he thought that it would be as fast as my old 2007 RM125 enduro spec. He soon found out that he might aswell of had a boat anchor on the DT lol

@calum You forget an Enduro is road legal, it must meet the conditions and laws required to go on the road. However, Enduro bikes are not always required to follow emissions regulations, that mostly depends on what country and region you are in. For example, in Auverge (france) where I ride, enduro bikes have to follow the Euro 3 or 4 EU regulations depending on their model year. Enduros are not made for a track, they are designed to go on a set course not normally shorter than 10 miles that generally at certain points requires you to go on the road, mostly when crossing from one trail to another. So you saying Enduros aren't made to go on the road is not strictly true.
