I bought this FMF exhaust for my sons XR 100
I'm super impressed with the power and sound change. 100%
I bough this a month ago for a 2013 klx 110 perfect fit great bottom end power boost and great sound
This thing will add 69 horsepower to your minibike of choice making it into a bitchin performance machine
Pipe performs very well and in my opinion is built better than pro circuit ...
If I buy this FMF Powercore 4 will I need a new heat blocker so it can fit
Got this for my 01 xr100 and put it on myself. I do notice some lag when just revving it (like hesitation) and I was advised it may need carb tuning after installation. I have yet to get that done. But, going up a steep hill in first or second or popping a wheely my XR has more power than with the stock exhaust and sounds louder and better. Overall, I'm pleased with my purchase and would recommend this exhaust
Just ordered it my first time on this website and absolutely love what Motosport has and for great prices !! I wanted the fmf factory 4.1 but wasn’t in stock all I need now is a few motosport decals and a muffler plug !! and will be
ready to ride again thankyou Motosport you’ll be gettin lots of business coming your way !!! Thanks again motosport!
I got this awesome pipe awhile ago. It sounds beast as **** and I noticed a big difference in mid range power and topend as well. And let me add this is my 9yo sons bike and it’s a blast now thanks MOTO sport all around great product.
I got my powercore 4 from motorsport in perfect condition...on time too....very pleased with the pipe added lots of power to my crf100...especially on the bottom
