<![CDATA[Dt170 vs ktm exc 125]]>Who will win? Acceleration and top speed race. A well tuned dtx Athena 170 with performance exhaust(stock carb) vs the ktm exc 125 full power?

Might buy a jet kit for the bike and mess around with a few plug chops this winter.

Most it's done is just under the ton on the clocks, at the redline in 6th. It's funny cuss in the 125 sports bike world the nsr is regarded as one of the slower bikes. I'd have loved a crm though, just there so thin on the ground.

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.

Is the NSR derestricted properly ? Should pull atleast 110 derestricted

I removed my airbox snorkel and upjetted carb, very good sound and possibly abit more power? Not noticeable mind but does sound brilliant.

Its the mixture screw and pilot jet you need to tweek when you remove the snorkel on a DTR mostly as they bog down at low rpm due to the air rich mixture, dial it out and you get a lot better low down acceleration.

@scrimsmustang don't think it will win over a wr200 but you're right, they are powerful. I Wonder how Honda manages to squeeze out 30 bhp and how Yamaha only ~20 bhp. Seems odd.

CRM will piss over the WR200 ive had a fair few 200,s and the Honda would just laugh at the 200, 125 or not.

Also Aprilia RS125's do this. They take a scoop from the nose cone, and force it into the air box lol.

But you can get nasty negative air pressure coefficients that cause adverse effects.

To me is looks to be pointing in the wrong direction and I always feel that the rider and seat will reduce airflow around that area too. But I guess it is not too restrictive as all bikes perform extremely well with the air box and snorkel set-up. Has anyone tried small air scoops on the side of the air box to draw air into the box at all ???

Airbox is quite restrictive when your tuning these,

but, Induction plays an important role in the exhaust note.

They blow up, sure they are prone to failure. But that's cause people shove loads of power into them lmao!

This is a clip of my bike, sounds better in real life mind

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.
