View Full Version : Exhaustpipe for Aprilia habana/mojito
02-26-2003, 08:10 PM
Sorry for posting this topic in this forum, but I am desperate. So here I go: What is the best pipe for the habana with 70ccm kit? I have a technigas basic mounted, but that is not a good pipe. Is the technigas silent pro better? Or is there another brand of pipe that will fit, with no fitting issues, that is high performance? Will be very happy for all input.

Troutmaster....this is a good question as the Mojito is supposed to be coming to America soon and will be added to this forum upon its arrival. I would like to know the specifics of this engine....vertacle or orizontal? Air or liquid cooling? What cylinder kits work good for street use? What carbs? What size rollers? What pipes?....any performance tips from owners are welcome here!

Its a horizontal mounted engine and it is air cooled. Stock performance is poor. But if you remove all restrictions it will perform well. It is then pretty fast and very silent. Good thing here in Norway where police and other controllers are very keen to stop people having a scoot performed over 45kph. In this configuration it will give top speed 100kph on the speedo.(80kph in real life)
The restriction are: washer, an extra expansion pipe on exhaustive pipe(you cut it off, and weld the hole, an weld it back on). This way no one can see that it is modified. There is also a restriction in the pipe where it meets the exhaustchamber, just screw them apart remove the restriction and screw it back together. That was the cheap version her is the more fun and costly version: polini 70ccm kit, 17,5mm dellorto(no point going bigger, and it also fit the original electrical choke, so no choke modification needed. A little modification on the throttle wire, no biggy), malossi carbon reeds. malossi multivar with big yellow mainspring and 6.1weights, kevlar belt and polini secondary gear 15/40. This will cost you a little on the acceleration on the first 2-3 meters, but then it kicks in and just goes really fast. And accurate speed reading I do not have, but on the speedo it shows 125 kmt. And 80kph up hills are no problem. Oh, I almost forgot: drill a hole on each side of the airboxintake 8mm big(make them smooth, and as like the original intake as possible, to avoid turbulense). I am also thinking on getting the malossi complete fly clutch to try and compensate for the loss in acceleration, I bought this for my sr ditech and it is worth every penny. I bought the tecnigas basic pipe because it looks like the original pipe(again police), but I know that it is not a performance pipe, the original exhaust pipe has the same performance unrestricted, and it is catalytic and very heavy. With this modification it is not possible to hear that this a pretty heavy modification. The sr ditech with polini 70ccm and gianelli pipe is in fact a bit more silent. But please, if anyone out there has any suggestion for another and much better pipe, please write. I am thinking on the technigas silent pro, but it looks a bit like the technigas basic so I am not sure what to do.

When you run in the polini kit, use a additional 1.5% oil directly in the fuel the first 50 kilometers. After that use 1% additional. The stock mixture is about 1,7-1.8%, this is NOT ENOUGH. You have been warned:smokin:

what engine do you have? a Minarelli? Piaggio? Morini?
try looking over Polini's exhaust systems i'm sure there's one that'll fit your needs. i wish i still have that full product catalog with me.:(

Thanks for all the info. I am just trying to be ready with a good assortment of parts for when they arrive in the USA.

Just a correction: It should be polini 20/61 secondary gear. Part number: 202.1369. There are almost a endless list of high performance part manufacturers to this scooter. And if it fits the suzuki katana AC it will fit habana/mojito. The best cylinder kit is possible made by Hebo, they make one in aluminum(better heat dissipation) But for what I know there may be others that are even better than Hebo also. And the scooter is very comfortable to drive, excellent suspension. But if you are taller than 1.85cm, then this is not the bike for you. And there is only room for a "half" helmet under the seat.
