From the few picture I observed it looks like it runs alongside the right edge of the skid plate not at all under the engine. The exhaust, to me at least, looks like the only unfinished part of that bike, so who knows for sure. I really like it myself. Well except for the fact that Royal Enfield produces it.....I don't know about that low-hanging exhaust, routed under the engine... Not sure I could take it seriously because of that issue. If they changed the exhaust, I COULD be very interested.
I've read 28 horsepower with 24 foot pounds. Now who knows if that's supposed to be crank or rear wheel...or if it will be accurate. If it's accurate and it's at the wheel, I'd say that'll do just fine. The DRZ-S makes 32 and 24 at the wheel. Even 24 foot pounds at the crank is half-decent though, IMO. That's six more than the strongest Japanese 250 dual sport.420 pounds with a 25 or maybe 28 horse, 410cc motor. I bet my TW would give it a run with a power to weight ratio like that.
