Love it!

i love this bump in my seat! i put it right where i want it and it works great! no shaving the seat down or anything just pull the paper off the bottom stick it on and put the cover back on! easy to install and holds you it the place you wanna be on the bike!

Great product

Fit perfectly on my CRF450. You can adjust the bump to any position that is most comfortable to your riding style. It really helps keep yours weight up on the tank more.

Factory Effex The Bump Seat Foam

Good

Installed quick and easy, looks good and fits nice under the factory seat cover. Adhesive is a nice touch to keep in place.

Williamsport, PA
Very helpful!

if you like being in place and want to get away from the sliding back on the seat from the power of a 450.. this can help keep your butt planted. easy to install and better with a high tach seat cover.

This thing fit and feels great. It'll hold you inplace when hard on the the gas!

A: the Factory Effex Bump Seat Foam is added on top of the existing foam to better keep the rider in the desired position on the bike.

I would recommend taking the seat to a custom upholstery shop and see if they can replace the foam on the seat pan for you.

Q: Stock cover

will this bump work with the stock cover on an 07 crf250r?

A: Yes, that's what we used. It should be set out in the sun or use a hair dryer to help stretch it a tiny bit. I also trimmed about 1/2 inch of foam from the front edge of the seat so it would pull back and lay right. We are very pleased with the results. My rider likes the front edge of the bump about 8" back from the front edge of the seat. This provides a saddle to plant him in place to attack the turns. He sits down in front of the front edge of the bump in turns.

A: Yes, this should work with your stock cover. It's going to be really tight getting it on though.

I have a 2002 cr 250 w/ a one industries "complete" seat. Will this seat bump work for my application?

A: Yeah it should, if it is too large you can always take a box cutter or an exact-o knife and cut the foam. just be careful to do it slowly or you will risk ripping it
