| I love to ride my dirt bikes, and the thing that I | | | | loud my bike was, and he said it was probably the |
| would hate the most is to be shut down by some | | | | quietest bike on the track. This was surprising to me |
| no-fun, party poopin', selfish brat because they think | | | | because KTM's are usually loud, especially when they |
| my bike is too loud. It's pretty sad considering how | | | | have aftermarket exhausts on. FMF states that this |
| quiet most dirt bikes are compared to trains, jets, | | | | silencer lowers the sound output to about 92 |
| and, of course, Harleys. This is what has come down | | | | decibels. I didn't have a sound meter, but can |
| to in the sport of motocross though, so if you want | | | | definitely say it was close to 90 db. |
| to continue riding then you better do something | | | | My YZ125 on the other hand, was a little bit different. |
| about it! A simple and inexpensive way to do this is | | | | It idled quieter, but it still had a little bit of that 125 |
| by slapping a spark arrestor silencer on your dirt bike. | | | | snarl once it got on the pipe. When I was riding in the |

| state trails, as well as enduro and harescramble | | | | exhaust had to be directly pointed at you for it to be |
| racing. | | | | loud. The result was the same for my Honda 125. |
| Even worse.... public tracks, riding parks, and popular | | | | What About Power Loss? |
| trails are being shut down. I'm not a big fan of | | | | This is the biggest question when deciding whether |
| putting a spark arrestor on my bike just because I | | | | to buy an aftermarket spark arrestor or not. I was |
| don't think dirt bikes can start fires very easily. That | | | | scared that it would take away some needed power |
| is, unless you literally pour gasoline on a tree and stick | | | | from my bikes, especially with what little power |
| the exhaust right up to it. I DO feel more | | | | these 125's had. From all the riding I did, I didn't notice |
| comfortable using one at certain riding places though, | | | | any power loss on the bottom-end. The mid-range |
| because I don't want to get in trouble because some | | | | still felt the same as before on all of the dirt bikes I |
| grouchy neighbor tattled on me. So, I got me an FMF | | | | tried. For the top-end power, I will say that it felt like |
| Turbinecore Spark Arrestor to quiet my lovely | | | | I lost a little bit of power up top. It really didn't feel |
| 2-strokes down. | | | | like much though, and it might just be in my head |
| I used this spark arrestor on my KTM 125SX and, | | | | because the bike was quieter. So all in all the power |
| YZ125, and CR125, and the results were all very | | | | surprisingly did not really change. You would have to |
| similar. One of the first things that comes to mind | | | | use a dyno to see the actual difference in numbers. |

| would take away power from your bike. I thought it | | | | Well let's look at what you will be able to do with this |
| would, but I had to use it if I wanted to ride in | | | | silencer on your bike... You will be able to ride on |
| certain areas. | | | | state trails because it has a spark arrestor and is |
| How Loud? | | | | USFS Approved, you can race enduro's and |
| The first thing I noticed when I put the FMF | | | | harescrambles, it will make your neighbors happy, and |
| Turbinecore on was that the bikes idled a lot quieter. | | | | most importantly it will help keep more riding areas |
| I could actually talk to someone right next to me | | | | open. Plus, the FMF Spark Arrestor is a whole lot |
| with it on instead of having to shut my bike off. I | | | | cheaper than any four-stroke exhaust. If you are |
| used it for trail riding, motocross racing, and just for | | | | riding in noise-conscience riding areas then this is the |
| playing around. When I raced with it on my KTM I | | | | part to get if you want to continue riding your dirt |
