  • Pro Circuit Factory Sound 304 Silencer

    Pro Circuit Factory Sound 304 Silencer

    Adam in NH

    Worth every penny

    I’m a research guy and was gonna learn everything to learn before buying my silencer. Was originally looking a the fmf powercore 2, and especially the powerparts version. This caught my eye because it’s 20$ cheaper, and I like the general shape and design better. When I first got it I was astonished by the size and weight, it weight probably 3/5of what the stock Ktm silencer weighs and it is much shorter and smaller diameter. The Ktm and fmf exhausts are an oval, increasing the packing volume while this pc silencer is a circle with less volume. From the first startup it totally changed the sound of my bike. The idle was deeper the tick over on deceleration sounds like a factory race bike. Not overly loud on acceleration but has much more of a crack and sharper sound than the original. It makes the low end pull a little better with no noticeable loss up top. Whole bike feels faster throughout the range because of the sound and feel. Once I’m riding hard on trails it just keeps putting a smile on my face, just hearing the sharp crack of a 2 stroke echoing through the trees. I did have to put some zip ties storing the pipe/silencer junction gasket thing, but those usually leak and I’m surprised mine wasn’t already. At the end of the day, would I put my stock silencer back on? Never. Everything I could have asked for, perfect fit too. Will be getting the platinum 2 pipe this winter too so I start the season off fresh with a perfect combo.

    Pro Circuit R-304 Shorty

    Pro Circuit need anyone say more. This product was just what the KX-85 needed. All-around performance has improved, and the sound can’t be beat.

    great silencer

    I had bought an pro Circuit pipe for a two stoke I used to own and loved it, since converting to 4 stroke I decided to try out Pro circuit again, this pipe is great not to loud and gave me everything I was looking for.

    Pro Circuit Linkage Arm

    stuart in MD

    Build & quality are great, results, not so much, wa...

    Don’t believe the magazine reviews on the 2018 RM-Z450 this is not needed for a balanced suspension ! once installed it makes the forks very harsh & no adjustment can fix, A revalve of the entire suspension is required to remedy. Setting your sag @ 110mm is all that’s needed if you don’t intend on having your suspension reworked
