I suggest you stick with the +4, coming from a guy with a few mods and a +6 who rides in dunes.

 

I agree with the +4. I haven't ridden anything longer but I know that even with a +4 I can drag the chassis skid a lot more on the crest of a dune versus stock. I also think the +4 keeps the bike feeling lively yet stable. Just my opinion of course.

 

one thing to think about is what is your % of riding in the dunes vs the logging roads. I had a plus 8 on my 660 and liked the feel but hated the turning. (way bigger radius). I still had a wheelie problem even after the plus 8 so now i am a plus 14. The strange thing is the radius is about the same as my plus 8.

I would go to a plus 6 if i did about a 50/50 split, or if the dunes was the bigger problem keeping the front end down.

hope this helps..

 

I am trying a -3 swinger this year for oval racing, trying that is.............

 

Wow, I would never guess that short of a swinger would work. Wouldn't that make the steering really twitchy (responsive)?

Guess I just answered my own question...

 

I have a +6 for the dunes and it will still play in the trails, but it does push the front end on some tight turns. Our other 700 has a +4 and we are able to sling it around pretty good and i don't really notice the push with it.

 

I am leaning towards a 6", 90% of all my riding is in the the dunes. On the logging roads I should be able to whip it around ton the loose gavel, so turning radius shouldn't be a problem.

 

A +4 on a 660 raptor is equal to a stock swinger on a yzf 450! That shows you how under sized the swingers on the raptors are. Ive ran a +5 and loved it for playing on and just every day riding. Im currently running a +14 on my 'play/duner" bike now and at times still trys to come up.
