Our new Darken chain slider for 18/19 Gasgas and 21+ Rieju, was developed to solve the large amounts of mud expelled from the chain. This mud gets packed up underneath the carburetor, back of cylinder head and over the oil fill bolt.
This Darken chain slider Should help Improve airflow around the back of the cylinder head in muddy conditions, in turn helping to keep your bike running cooler in harsh conditions.
Using this Chain Slider should result in easier cleaning & easier oil changes since you're not trying to remove baked on mud, that's turned hard, from the engine heat.
