The OEM in China is Hensim, and we used to have 'Hensim' as a manufacturer/distributor in the US in City of Industry in the greater L.A. area. They got in trouble with the EPA as numerous Chinese brands do, and they pulled out of the US years ago. They regrouped as Ricky Power Sports, or RPS, and are now in the greater Dallas metropolitan area. I would start with them. The Viper is unique as far as it being more of a small full-size bike than a pitbike. The advantage is that the Viper is still around so you should be able to source parts directly. I do recall members with parts questions for the Viper being shocked by parts prices, so be prepared for that.
