Timming chain


I need to replace the timming chain in a 2004 trx 400 ex. I was told to buy a trx 450r timming chain because it is stronger cheaper and a dirrect bolt in replacement. Its true that the chain is half the price of a 400, however does anyone know if it fits without any mods?

I have heard of the same thing but never tried it. To me just get the part that fits the engine and it will be right the first time.

The CRF450 one fits. I'm not sure about the TRX450, but I think it should be the same.

We use the 02-08 CRF chain with no problems. I don't think the TRX will fit.
