VESPA BIG BORE EXHAUST DYNO RESULTS

-

Due to an oversight last month in our Vespa Big-box Test article, it wasn’t so easy to read the max power and max torque figures for each exhaust, so here are the numbers for those who need them: Standard PX200: 9.93bhp @ 5330rpm, 11.6lb-ft @ 4234rpm BGM Sport: 11.83bhp @ 6343rpm, 10.49lb-ft @ 5562rpm BGM Tour: 11.27bhp @ 5528rpm, 11.46lb-ft @ 4826rpm LTH/TSR: 11.36bhp @ 5752rpm, 12.44lb-ft @ 4240rpm Pinasco Touring: 11.2bhp @ 6369rpm, 9.83lb-ft @ 5594rpm Pipe Design: 11.46bhp @ 6209rpm, 10.07lb-ft @ 5589rpm SIP Road 2: 11.24bhp @ 6165rpm, 11.72lb-ft @ 4733rpm SIP XL: 11.69bhp @ 6229rpm, 10.33lb-ft @ 4719rpm Sito Plus: 10.59bhp @ 5903rpm, 10.95lb-ft @ 4495rpm Remember though folks, you need to read the graphs from last month’s Scootering to see what suits your needs as some exhausts like Pipe Design and SIP XL rev out towards 7500rpm in our third gear run, while others barely exceed the standard pipe at little over 6000rpm.
