The author describes the performance of the Peugeot version of the pipes, but the Motobecane version of the pipes have very similar performance characteristics. These articles are geared more towards 50cc kit tuning. When referring to "bigger kits" or "46mm cylinders", it means the 70cc and anything larger than 50cc kits. Likewise, when referring to "stock" or "original" cylinders, it means the cylinders that came on the bike from the factory. In the case of the Motobecanes, it might be worth noting the author was most likely referring to the AV10 bikes rather than the more common to us North Americans AV7.

This exhaust is one of the first long exhausts offered by Ninja. It is famous for being a higher RPM pipe, but at the cost of low RPM performance… It is a rather noisy and relatively not very aesthetically pleasing pipe. This exhaust would probably be good for 50cc kits, and not terrible for stock cylinders or the bigger kits.
G2 Ninja (commercial)
- Price: $165.00 at treatland
The successor of the Ninja G1 pipe, this exhaust is excellent. It has a high power band, assuming you can reach it. This exhaust works best with high RPM setups. It is not advised to use it on a stock cylinder, and does not preform as well as others on the bigger kits. This exhaust is a very good exhaust for 50cc kits, on the other hand its price remains relatively high compared to other high quality, low priced pipes.
It is aesthetic pleasing, but is relatively noisy.

This exhaust has nothing has to do with the category G3 French racing, but was labeled as such simply as a marketing strategy to the French tuners. It is the most recent exhaust pipe from Ninja and it is the best of the three. While the G1 and G2 lacked in low end, the G3 makes up for it. With awesome low end, great mid range and good top end, this exhaust is good through the whole power band!
It works very well with a 50cc kit with it's great low and top end, performs nicely with bigger kits, and while not the best, even effective with the stock cylinder.
At the aesthetic level, its original form will not please everyone and it can be objectionable to the eyes of certain builders as it has twists. When compared to other pipes of it's quality, it is one of the least expensive - less than the Bidalot RR, Doppler, Ninja g2, etc. The sound of this exhaust is exceptional. A beautiful, deep note at idle, but screams to life on the track! An excellent investment!
Gianelli Black Gun
- New price: approximately 85 Euros
This exhaust is without any doubt one of the exhausts which agrees highest, it offers a high excellent mode with kits 50 also supporting the high modes such as the Malossi (excellent combination) for example… It is also very good with other kits 50 supporting in high mode, the problem remains that it appears exaggeratedly hollow in bottom and miserly in recoveries… This exhaust is really not advised with a kit diameter 46, any possible agreement, and relatively means on origin…
On the level of the price it is more than reasonable, priding to be one on the exhausts honnereux… noise Level, it is relatively noisy (passable all the same) and classic, it does not have a particular stamp… To conclude, an excellent exhaust for little which one agrees to sacrifice the low modes, unless one has a pulley clutch of mark, of a good vario etc…
- New price: approximately 95 Euros
This exhaust east enfait the counterpart exact of the Gianneli black gun, it is just more expensive (because of notoriety of conti in the world of the mécaboite)
- New price: approximately 140 Euros
This exhaust is one of best on the market because it is one of the rare exhausts length has to agree relatively low while preserving performance has high modes correct! Indeed, this exhaust agrees to perfection with a cylinder of origin but also with a kit diameter 46 with which it shoed wonders! It also proves to be a good compromise with the kits 50 which have for defaults to miss gouache in bottom, thing that this exhaust is given the responsibility to rectify (default perfs a little less honorable have high mode… but Ca remains very correct).
At the aesthetic level, this exhaust finds being relatively pretty (all is a question of taste)! On the other hand, sonority is rather noisy and hollow, very unpleasant I find… Moreover rockwool has to change very regularly under penalty of a rather unbearable increase in the decibels… To conclude, this exhaust is the best than one can find for cylinder of origin and kit 75, it also proves to be a good compromise for kits 50… the only big problem resides in its very high price…
- New price: approximately 110 Euros
Let us be clear from the start: this exhaust is not “worthy” of the mark Bidalot, I am explained. For a relatively high price, price does not offer incredible performances: not terrible in bottom, passable in top, offering suitable recoveries. This exhaust does not deserve its price. It offers performance on par with a cylinder of origin (approximately +10 km/h), has evil has to agree with a kit 50 (rather not badly in the average modes…) and hardly does not appear better with a kit diameter 46… Same granted to kit 50 of the same name (Bidalot RR), this exhaust works less although the Ninja g3 for example… seek the error! Moreover, the cartridge is attached is extrement shitting has to unsling, which can push has to invest in a cartridge unslung “carbon” which is not given… (useless to specify that without unslinging the cartridge, this exhaust proves to be a calf…).
Aesthetic level, this exhaust is rather pleasant because original compared to the others (it is not style rolled/welded but of the style 2 shells not welded) but especially because it is equipped with famous the blue cartouche Bidalot… This exhaust is rather noisy and releases one sonoritée particuliere, rather acute which will not like has the entire world.
To summarize, this exhaust does not deserve absolutely an investment of your share, same coupled with the kit of the same name… a great disappointment for me laughing
- New price: approximately 150 euros (of + in + difficult has to find)
With this exhaust, Bidalot arrives has to show that it is not forcing in the west as regards exhaust (as with the RR). Indeed, this exhaust of excellent is quality, it offers performances really epoustouflantes (an acceleration enormous follow-up of an excellent point! Phenomenal recoveries has high modes!) with very large kits 50 such as the prepared RR, G1, G2 because it agrees very high (+ 12000/tr min, the commercial exhaust which agrees it + high! =)! Useless to specify that this exhaust is not useful strictly has nothing on a cylinder origin which will be able by no means to exploit it, as on one 75 which does not correspond at all since being mainly turned towards bottoms and average modes… aesthetic Niveau, this exhaust is splendid, a nearly perfect line equipped with a long silencer (absorption) of any beauty!
On the noise level, this exhaust is extremely noisy but pleasant… Pas problem thus with the countryside but a little bit plus tended downtown…
To conclude, this exhaust is the best than you can find (if you still find it… the production were stopped there is little) for little that you had a large kit 50! If it is not the case go your way…
Kenji has pump
- New price: approximately 75 Euros
This exhaust has a characteristic compared to the others: its pump! It agrees has wonder with a cylinder of origin because this exhaust agrees very low, it offers a demensielle acceleration and an average point! For kits 75, this exhaust is also the best for acceleration pure, it agrees has wonder! On the other hand, with kits 50, this exhaust agrees rather badly because it under exploits too much the high modes… the attached latter feeling! At the aesthetic level it is enough bizarre, personally I do not hang to the style, the cartridge is riveted (and attached occasion consequently, to repurchase an emergency absorption!) and the system of pump can practical (oil escape, fragile…). On the level its, it adopts a pleasant sonority, not too high, slightly serious…
To conclude, this exhaust is perfect for which seeks the maximum of acceleration and low mode, perfect for the city, exhaust however appears its limits has high mode or it does not defend a whole well…
Leovinci Speed aluminum
- New price: approximately 90 Euros
it is a bottom-of-the-range exhaust: well for small the budget, he exploits especially top speed, same if that is not obvious… Once unslung, one gains can be 5 km/h, and by changing the cartridge (yes c´est really a cartridge of m ****, baffles), can be 10 km/h. The supports are with the elbow, between the exhaust and the cartridge, and with the same cartridge it. To summarize, it is a cheap exhaust, (well? ) for the cylinder origin, but once passed for the kit one needs l´oublier…
