IMO if you are TRYING to be a better m-x racer that means you probably are riding the quad pretty "heavily"
meaning pounding into faces of whoops, casing into tops of doubles coming up shorter on landings from jumps ect... ect...
Riding "lighter" will ease the stresses put into the frame usually! Your skill level increases you don't pound the quad as much and all and just generally ride smoother and faster! Not saying you're not a good rider just making an opinion to what you typed out here.
I know the OLDER LT250r's had some real issuses with weak front ends, mostly '85-'86 and racers of any skill level had to gusset pretty much,LOL!!! My '88 LT250r wasn't to bad, but I started with decent front shocks and all right from the get go! I did gusset 1 of my '88 front ends just in case. It was my first '88 that I owned and had just sold the older '86 and thought I better do it!!!
I don't know for sure how these new frames are holding up. I would hope Suzuki had learned from past mistakes and did frame structure testing beforehand with computer controlled robotic hydraulic cylinder's on major stress points of the frame! I saw this type of testing being done personally firsthand before the Aluminum framed LRD type stuff was released into production. The company I saw it at was working with crotch rocket race teams and had all the test equipment on site! Basically like a "frame dyno" if you will! LOL.
Has anyone seen if the Team Suz./Yosh. quad's have gussets? Then again you're talking about rider's with exceptional skill level's and the BEST suspension money can buy! So...
Are these gusset kits really a sales gimmick or do these frames hold up? I guess time will tell for sure if the factory did they're homework and made this stuff tuff',LOL!!!
Might not be a bad idea for you now just as kinda' an insurance policy! Then again some people like to "Roll the Dice" ALOT!!!
