Honda GB 500. 33hp. 350 pounds. Yamaha Sr500 33 hp. 359 pounds.An original 250cc Royal Enfield Continental GT 21hp and ? pounds.New Royal Enfield Continental GT 500 29hp and 405 pounds.How hard would it be to get a couple more hp out of the new engine? The Harris frame is awesome and I like the high quality components used on the motorcycle. I think the new GT is outstanding and the only thing holding me back from buying is I already have too many motorcycles in the garage. What a gorgeous motorcycle.
