What front bumpers give good coverage and look decent also. I have a feeling that anything honda will fit nicely they're just a little ugly for my taste..... Thanks for any info.
I remember Matlock or Caster saying something on here why Honda used the plastic bumper. Something with the vibration causing cracking.I believe the plastic bumper is due to lower cost. Does not the Raptor have a plastic bumper too? I do not recall any Raptor riders complaining about cracked after market bumpers.
I've got news for you guys- The cracking is not PRM's fault.
The frame on the 700 flexes alot. This is what is causing the cracked welds. The frame was designed like this from Honda and this was the reason they come stock with a plastic bumper that allows for the flex. It was designed this way with some flex or "give" in the frame to keep from breaking other parts. Other quads are the same way and thats the reason many people gusset or reinforce the frames on race quads. We were told by Honda not to do this on the 700 because the flex was needed.
We found this out very early on in our testing because we were breaking or cracking the bumper mounts after installing an aftermarket bumper for racing. We had a couple of different solutions to the problem-
1. Drill out the stock welded nut on the bumper mounts. Use a rubber grommet and sleeve type set up that allows the bumper mounting bolts to flex with the frame. This is how all our race quads are done.
2. On my personal quad I tried something different. I cut the bumper mounts off the frame and welded tabs to the frame. I then mounted a TRX450R Roll-Design bumper to those mounts with a bolt setup that would allow it to flex with the frame. It is noisier and not as good as the rubber grommet setup.
PRM makes a great product. It does not matter what type of aftermarket bumper or grab bar you decide to mount, it will end up cracking in the long run if you don't rubber mount it and allow the flex.
The rear grab bar area of the frame also flexes but not nearly as much as the front of the quad. I don't think you will have many cracking issues with most aftermarket grab bars. The only type that may have an issue are the kind that don't allow any flex. We have been running PRM's grab bar with the little tool bag mounting area for over a year. The very first one we used finally cracked after running thousands of race miles on the the quad. I don't know of any other grab bar that would have held up to that punishment. I will continue to run PRM stuff on my quad.
