Fabulous customer service

This was my first experience with Motosport, although my son and grandsons use it frequently. I was very impressed with their courteous and knowledgeable customer service.
I knew nothing about what I was ordering except what my 12 year old grandson told me, and the Motosport representative was patient and helpful.
I also did not receive the item even though the shipping company said it had been delivered. This was a Christmas present and this 12 year old boy was going to be very disappointed. Motosport resent another one special deliver at no cost to me.
I was very pleased and would use them again.

Pro circuit shorty

Pipe looks and sounds great on my bike, it's a way better then the busted-up turbine core that's been on my bike since I bought it.
The fit was perfect on my cr250 and I am 100% happy with this purchase.

Great look, awesome sound and performance gains

Love the shorty muffler for its crisp sound, which is surprisingly mild btw as compared to most. Easy install and perfectly fit the bike and the Pro Circuit exhaust. This and the exhaust really allowed the bike breathe better over stock, puller harder in each gear and more responsive. A couple of sections my son was struggling with by having to short shift into 3rd he is now powering through in a taller 2nd gear with ease...he is riding with more confidence.

Totally worth it

I noticed the difference in sound right away, I think it opened the bike up more on the bottom end. Definitely worth the buy, in my opinion it seems better than the fmf shorty that I had previously.

Great

Match this up with a pro circuit platinum pipe and your good to go. This is very easy to install. And looks great. Gives my yz125 a little bit more top end power. And it sounds amazing. Every time I start up my bike I smile.

Good silencer!

I have a pro circuit works pipe on my '04 RM250 which i bought secondhand. The bike came with a Pro Circuit spark arrester silencer which i rode with for a few months. I decided to finally get a motocross silencer and man! Not only is this Shorty about 2 lbs lighter than the spark arrester, it took the tame power band of the RM250 and gave it some hit! A little more on the bottom, but mostly noticed that the powerband actually "hits" now in the mid range. Noticed no difference on the top end but i barely get out of third gear on the local tracks anyway!

Pro Circuit Shorty Silencer

I bought this for my son's cr250 hoping that it would give a little more power at his hill climb competition, but didn't notice much difference at all from the forest approved spark arrester silencer.

Great pipe

this pipe is great, if you only or still have stock exhaust on your bike, if you buy this pipe you will notice a big difference in power. it has a nice sound to it, looks great on the bike and it was easy to install , i have this paired up with the pro circuit platinum pipe on my yz 85 ,,huge power gains. this just makes the bike rip even harder. great pipe, and in my opinion its better than fmf

Great Silencer BUT

great siencer lighter, louder, and gives it a bit more lower end grunt. the only problem is i need to re jet my carb because my jets are stock and its making me foul plugs quick so i would suggest getting a re jet kit with this silencer

I have a stock 2016 kx 100 and I'm looking the get the r304, will I need to rejet my bike in order to have the r304 on it?

A: No, you likely will not need any changes. Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this PC silencer. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

Q: Shorty or regular?
1 year 7 months ago
I ride a 2014 KTM 250 XC-W (E-start) I mainly ride tight wooded trails and cross country enduro. I love the bottom end on the bike (stock exhaust at the moment) should I get the regular sized R304 or the shorty? Also was wondering if the silencer will fit on the stock expansion chamber? will most likely upgrade to the Platinum 2 pipe in time, or should I just buy the full system all at once to avoid more rejetting?

A: The Shorty will give you more throttle response and low end power. Because it's smaller you'll see even more weight savings and a louder sound level. The Pro Circuit Factory 304 Silencer Improves top-end power. If you are riding in areas that require a U.S. Forest Service approved spark arrestor you would want to go with the Pro Circuit Type 296 Spark Arrestor.
Fitment with the stock pipe can not be guaranteed, but you shouldn't have a problem. And as far as jetting It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting.
