I was at a race and we were lookin at this pro guys z-400 we noticed it had extra suport in the front of the fram that has been welded in there. the guy said after a week of racing it the hole front end fell of and was hanging by the shosks. We imedialty looked at my friends z-400 and it just started cracking so his dad didnt let him race. he took it in to the suzuki dealer and they gave him a new one in four weeks. ive also heard of other peoples frames cracking up front just wanted to no if you guys have heard of it and if they are going to make a new frame desien soon.

 

Last I checked, Bartlett Racing had the info on gusseting the frame to cure the problems.

 

Lonestar Racing sells a gusset kit for $300
