I've yet to find fault with any of Brent's products, but I didn't buy a chain from him. I bought mine from parts411.com. Unfortunately they've since raised their prices from just under $100 to something like $125-130 for a Gold DID VM2. Next time I think I'll just buy the entire Triumph setup that comes with the chain and both sprockets from one of the online discount Triumph dealers.
I'd buy from the local dealer if they were any good, but I've always been treated 2nd rate there since I didn't buy my bike from them. The fact that they didn't even carry Triumph motorcycles until a year after I bought mine seems to be lost on them.
