Thread: DD1200 Arrow Titanium pipes !!

Here they are. AF1 got them and put them on my bike.

Had before and after dynos run and with and without baffles (the bike runs best w/o the baffles). Not much time to post, but the bottom line is they allow 123-125 RWHP peak on the 1200, and they usually are up about 3 hp and a little more torque thruout the power curve. However the ECU runs lean just about everywhere, but especially from 6000-7500RPM, where a stock bike EXCEEDS the Arrows. The pipes really enliven the beast from a standing start to 6000RPM over stock, you can positively feel the difference in the butt dyno.
Need to be able to tune the ECU and apparently AF1 is close to that becoming a reality.

Rats, my MacBook is giving me fits and not posting properly links to photobucket...... no time to sort it out.

Looking good - bet it sounds the part - how much weight you saved?

Looking really sweet, big weight saving?

Came in at 8.5lbs savings

As Ed said; they came in at 8.5 lbs weight saving.......howeverif the baffles are removed, thanks Ed,you lose an extra pound for a savings of 9.5 lbs ! And again, the bike runs best with the baffles removed and sounds much better, deep-rumbling, like a big inch v-twin should. Not obnoxious like a straight pipe Harley. (Disclaimer: I have a fairly loud Harley)



I'll get the dyno up sometime soon, unless maybe Ed can post them and comment on the comparisons, strengths and weaknesses (map).
With the baffles out, it topped at 107.4 HP on the AF1 dyno, which Ed said reads 15-17% low when compared to DynoJet readings. That would be then
123.5 to 125.6 peak RWHP. That peak came at about 9,000RPM and only backed off a little by 9,500RPM.

All of the posted pics so far are with the baffles in. Took videos in the dyno room with a little digicam, but the intense wind and engine noise overwhelmed the camera microphone. The sound is positively impressive however.

dang....wish this came out a few days ago, I'd liked to have run the proper mapping

Date : 20/07/2011
Object : Dedicated Mapping Arrow Exhaust Accessory Communication number : 018 - Year : 2011 Model : Dorsoduro 1200cc Communication :

A new dedicated mapping is now available on the Navigator for the Dorsoduro 1200 vehicles which are equipped with Aprilia-Arrow Exhaust accessory code 899443

yep, just got released today....sucks it was released 2 days too late.

I told Centerline I'd load it for free if he wants to ride back down here, and I'll do another run.

Thanks Ed! How about that, 2 days too late for the install....... but.....
I rode on over to RPM Cycles near Dallas and they installed the ARROW map!
OMG !!!! I think Aprilia has the map nailed! The on to off throttle transition is not so abrupt, so it is much easier letting off some power in say a mid tight corner for a decreasing radius turn or whatever. The engine runs way way smoother at partial throttle steady state.
It positively kicks butt at launch over stock. There is no letoff of thrust in the seat-of-the-pants (butt dyno) at the 6,000 to 7500RPM range that the engine was exhibiting with the Arrows prior to the new map!!!! YAHOOOOOO

Am off for a family vacation tomorrow to the mountains of Colorado and am trailering the 1200 with us. I know, it's tough, but, well, somebody has to do it.
Anywho, will see about getting it back to AF1 for another dyno run in a month or so. I believe we will see a night-day difference in the data on the dyno.

He's got the dyno and gave the date to me. Don't think I have the time (packing for trip) to put the date and dyno up.
As for AF1 putting Arrows on their demo....Ed told me as far as he knows, he put the only DD1200 Arrows in the U.S. on my bike the other day.
