I'm a new guy here, and don't know much (yet), but I do know that:
1) Yes, Dirtracks is a Canadian company, aka West Coast Moto Shop in Langley BC.
2) They promptly shipped well made crash bars to me I'm very pleased with.
Not that I have a lot of experience to compare to, but these are strong bars, precisely made and bolted right up with the new, longer bolts that were included.
I bought the "full body" model with the wrap around cross bar, and they are rock solid.
The only thing I would do different is spending the extra to have them powder coated from Dirtracks instead of raw and painting them myself.
I would buy from them again.
