It would grow into one of the motorcycle industry's longest-running and most respected performance companies. Powroll earned its reputation by developing an innovative method of shortening OEM connecting rods, allowing affordable stroker crank conversions for overhead-cam four-stroke engines. The design delivered impressive horsepower gains while improving reliability, requiring few additional modifications and quickly becoming a favorite among racers and engine builders. Although stroker cranks remained Powroll's signature product, the company eventually expanded into a full line of high-performance engine components designed to help dirt bikes extract every ounce of power. Even into the 2000s, Powroll continued developing parts for the new generation of four-stroke motocross machines. However, the economic recession and sharp decline in the powersports industry during the late 2000s took their toll. After several years serving the vintage motorcycle community with remaining inventory, Powroll ultimately closed its doors, with its tooling, equipment, and property being sold by 2019. \u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e \u003cstrong\u003eProduct Details\u003c\/strong\u003e\n\n\u003chr\u003e\n\nLike all our designs, this one is treated with our signature ‘relic-ing’ process which includes our own secret recipe of hand-painted chipping, cracking, fading, and just the right touch of yellowing to ensure that it looks the part of a true vintage imprint.** We lay these works of art down on premium Bella+Canvas 3001 Unisex Jersey Short Sleeve Tees, one of the softest, best-wearing t-shirts available today, via state of the art direct to garment (DTG) printing which allows us to create a vintage effect that simply can’t be accomplished with other printing methods.

We recommend taking one of your current t-shirts, laying it flat and measuring it. The measurements in the chart below are taken with the shirt laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the shirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam. While our tees are all made using premium, pre-shrunk, ring-spun cotton, there can be some shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence, we always suggest going up a size. \u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003e\u003cimg class=\"alignnone size-full wp-image-606\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-size-chart.png\" alt=\"\" width=\"1275\" height=\"220\"\u003e \u003cem\u003e\u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003eAll sizes are provided in inches!
