Nothing ages a motorcycle faster than faded, chalky black engine paint. The S100 Engine Brightener 4.5 oz (part number 59-9312 (S100 part 19200A)) is made by S100, the motorcycle-care brand riders have trusted for decades to get their machines clean, protected and looking showroom-new.

What Is S100 Engine Brightener 4.5 oz?

S100 Engine Brightener (S100 part 19200A) returns dull black paint to a like-new look. It bonds to the surface as the engine heats up, so S100 says it won’t break down like other protectants and withstands washings and rainstorms. Use it on black-painted engine cylinders and cases, cables, rubber hoses, plastic components and many other surfaces.

Why Riders Choose S100

S100 products are designed specifically for motorcycles: painted tanks, chrome, polished aluminum, plastics and rubber all on one machine. Instead of using car soap that leaves film or harsh degreasers that dull finishes, S100 gives you a coordinated system: clean, prep, polish, protect. Every product is designed to work with the others, so your bike stays protected from the first spray to the final buff.

Key Features and Benefits

  • Restores dull black engine paint
  • Bonds as the engine heats, for long-lasting protection

How to Use S100 Engine Brightener 4.5 oz

Pro Detailing Tips

  • Work in the shade on a cool bike. Heat and sun make any product dry too fast and streak.
  • Use separate microfiber towels for paint, wheels and engine to avoid dragging grit onto your paint.
  • Keep cleaners, waxes and dressings off brake discs, brake pads, tire treads and grips.
  • Dry the bike after rinsing, with a towel or an air blower, to prevent water spots and get water out of crevices.
  • Finish with a ride or let the engine idle briefly to drive out moisture after washing.

Frequently Asked Questions

Is it safe on rubber hoses?

Yes. S100 lists rubber hoses, cables and plastic components among the surfaces it can be used on.

Can it go on brake parts?

Keep it off brake discs, pads, tires and grips.

Is S100 safe on all motorcycle finishes?

S100 products are made for motorcycle surfaces. Read each product’s surface notes. For example, Polishing Soap is not for painted or anodized parts, while Wheel Cleaner is safe on anodized wheels.
