Hey all! Just wanting some opinions on the best most reliable stock frame ever produced on a sport quad? I've heard a lot about the 250r frames but I wonder what others are just great and how they rank. I know my z probably ain't gettin the no.1 honors from no one but everyone give me an opinion on the best ones.

 

Cannondale

 

Cannondale - I believe it's an all alum. frame, and isn't the coolant running through the frame also?

 

Gotta go with the DALE here also , Oil runs through the Frame . A other is i believe an LRD frame thats made from titanium . For the 250r i think ?????????? but that looked trick as a sonagon.

 

250R or 400ex.

 

I would have to say Cannondale also.. As far as the stock 250R frame goes, I wouldn't give them very good marks. The stock versions of those frames may have a good design as far as handling goes, but they don't resist cracking very well. Unless you get them gusseted they won't hold up for very long if you ride very many rough trails or do a lot of jumping. That is one reason as to why there is such a big market out there for aftermarket frames for those quads.

 

Yup cannnodale , even though they are alloy they are super thick and heavy duty. R frames are good but they eventually crack in several areas if abused. Thats what mig welders are for.

 

The R frame is probably the best to go with. All the frame builders base the geometry on the R and most racers use this frame

 

Don't really have to abuse them for them to crack. I broke my 250R frame in 7 different places before I finally got an aftermarket one. They crack most around the swingarm mounting location and by the motor mounts. I have seen them crack where the lower a-arm mounts too.

 

The DS650 frame has got to be the strongest stock frame....... Not to mention what is in the desgn of it.
