Bought this for a ttr125. Combined with a new carb and more air, the unit definitely added more pep! The best part was the sound - the ttr sounds WAY better with this set up.

Picked this up for my daughters CRF110. Woke the bike up a bit and gives it a sweet exhaust tone, plus looks great with a perfect fit. Stock heat shield bolts right on. Such an easy install!
It’s a great exhaust. Makes the bike sound a lot better than stock and will rumble everything around you. I ride my trails every 2 weeks or so and my neighbors across my neighborhood can here it. I just have one question, what size jet do I need? It’s a 2018 crf125f and running lean
I bought his for my wife’s TTR125 and I her or I couldn’t be happier. Easy to install and changed the tone of the bike without making it obnoxious. Good pipe!
The exhaust was a direct fit to our 2003 Ttr 90. Installed in about 15 minutes. The only downfall we found was we needed a different jet for where we live. Increased the performance from the exhaust.
Not only does this exhaust system sound nice, it added an amazing amount of power to my son's bike. He has a Yamaha ttr-50 and I wanted to give it a little more power on the hills. Well it accomplished this and more. Added a ton of torque in the low end. He has not gotten stuck on a hill since. Also very easy to install. My 4 year old son practically did it himself, with just a little guidance from me. Highly recommended!
The product has lived up to it's description. Very happy with it and the delivery came before expected.
My sons bike is used for both trail riding and racing, so this is a good pipe for both since it has the spark arrester. Easy to put on and the primary heat shield bolted right up.
I ordered the fmf power core 4 for my 02 yamaha ttr125l and fit great and sounds awesome. Definitely recommend motorsport.com to everyone there customer service is hands down helped me with all questions before I ordered thanks a lot

Question:Q: My son just bought a klx 110 with the power core 4 already on it. The heat shield is missing. Is this a fmf part or or does the factory shield fit?Question asked 1 year ago
Question answered by PaulUser's contributor status: Top 10Question answered 1 year agoAnswer: A: This FMF Powercore 4 Complete Exhaust Stainless Hi-Flo Header does not fit the KLX110.
To help us to find parts to fit your KLX110, we will need to know the model year, and whether it is the standard model with smaller wheels, or the "L" model with larger wheels.
