    Sweeter than my mama’s peach tea

    No complaints. Was a little late, but it was communicated to me so I didn’t mind. Looks awesome. Easy fitment. No struggling at all.

    Great Upgrade!

    Bought one of these for my 1976 Honda CB750. I had my motorcycle mechanic installed it to make sure there were no issues. He commented on the sturdiness and quality of the product. Fitting and operation has been flawless!


    Another outstanding piece from cognitomoto. The stuff these guys make really put your bike on another level!

    Lools great and worth every penny

    I've heard horror stories about adding pods to the old SOHC 750's. They cause uneven airflow and the buffeting air at high speed can cause your bike to run like crap. This solves both problems because it acts similar to an airbox' equalizing airlow/vacuum between the cylinders, while still allowing maximum air through the filter to the carbs. Can't say enough about Cognito Moto's customer service either. Great product and even better company.
