MAY 2022

ISSUE # 274

Biltwell 100

The second iteration of the 975T Revolution Max platform , Harley ' s new MY2022 '' Nightster '' model is rather more conventionally styled than the Sportster S , staying closer to the legacy XL look - perhaps with a hint of V-Rod thrown in for good measure . Claimed to be starting a " new chapter " in the venerable H-D Sportster motorcycle story - one that started in 1957 with the original 55 ci , Model K derived Sportster - Harley is claiming a " leap forward in performance and design " compared to the prior ( theoretically ) lower-cost range of 883 and 1200 cc Sportsters that the company has now largely retired , " while remaining an accessible entry point to motorcycling and the brand .

( 95 Nm ) peak torque @ 5,000 rpm from the 97 mm bore x 66 mm stroke , 12:1 compression ratio stock configuration , but we already know from the early Sportster S customs that are now starting to emerge regularly that there is tuning a plenty to be had . " Hydraulic valve lash adjustment ensures quiet operation and eliminates the need for costly , complicated service procedures .
