1909CSA TiN Ring Set Single Ring for Wiseco 48.50mm

TiN Ring Set for Wiseco

This TiN coated piston ring set measures 48.50mm and is designed to provide a durable sealing surface inside high-performance small bore engines.

Overview

The Titanium Nitride ring set delivers a hard, low-friction face meant to seal combustion pressure and control oil on modified engines. Each ring in this TiN ring set is sized at 48.50mm, giving a precise fit for the matching piston bore. Riders and engine builders choose this TiN ring set when a single-ring setup is specified for their build.

Built For Performance

• Titanium Nitride coating adds surface hardness for reduced wear
• Single ring design reduces friction against the cylinder wall
• 48.50mm bore size matches the specified piston application
• Built to hold cylinder compression under high rpm conditions
• Ring face engineered for consistent seating and sealing

Fits These Machines

• for Wiseco piston applications specifying a 48.50mm single ring setup

On-The-Job Use

• Top-end rebuilds on small bore two-stroke and four-stroke engines
• Replacement of a worn or broken ring during a piston service
• Performance builds demanding a lower friction single ring setup
• Routine maintenance on race and trail engines requiring exact bore sizing

Specs At A Glance

Good To Know

Q: How do I confirm this ring suits my piston? A: Match the 48.50mm bore size and single ring specification to your piston before ordering. Part number 1909CSA should also appear in your engine or piston documentation.

Q: Why choose a TiN coated single ring? A: The coating reduces friction and resists wear at the ring face. A single ring cuts drag further, which suits builds chasing peak rpm.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
