For the R? You don't want to weld this aluminum frame it will weaken it....

 

No for a carb yfz, 2007 frame to be exact. Haha I can always count on you to help out Kilroy!

Yamaha YFZ450 Chassis Gusset Kit - Yamaha YFZ450 2004-2014 - Lone Star Racing - $175.00


Walsh has a gusset kit for $200

LoneStar Racing has one for $175

I'm sure theres others companies that have them too, and yes people were using them for MX to reinforce stress points in the frame, I'm sure if your a heavier rider and put the bike to its limits it wouldn't hurt to use a gusset kit but not really necessary in my opinion if you aren't racing/jumping

thats the link to the Lonestar install instructions to get an idea of what gussets come in the kit and to where they go

and this is the link for the Walsh kit install

LoneStar kit looks better then the Walsh IMO...more and better gussets and its cheaper

I agree that Lonestar kit looks really good!

 

I was considering it because it's a 10y.o frame but I haven't had any issues with bends, dents, or cracks so far. Thanks for the input.

 

it would be up to you, just consider your gonna have to spend $175 off the bat to buy the kit and either weld it on yourself or pay someone to weld it for you....and after all that you'd have to completely strip the frame down to get it powder coated or if your gonna be cheap about it you'll spray paint it but i wouldn't even think about doing that, id do it right and powder coat it

you'd be looking at roughly $600 for gusset kit, welding, powder coating

 

The bike is going to get stripped down and powder coated now anyway thats why I was considering to do it now. I just wanted to see if anyone else here has already done it and have experienced it saving their frame lol.

 

then if your already doing that it wouldn't be a bad idea to do the gusset kit

pretty sure it wouldn't hurt to beef up the shock, a-arm, subframe, steering stem mounts

id do it if i hadn't already powder coated my frame :icon_neutral:

 

I might just go with the LSR kit. The person that I'll have powder coat also does welding so I might kill two birds with one stone.

 

I'd get one, especially if the frame will be stripped anyway. I'm a bigger MX racer that had frame issues until I did a Teixeira gusset kit...no problems since then. I race a TRX but the same principle applies:
