The stock chain guide unit on the Suzuki DR650 usually doesn't last long if you ride your pig hard off-road. The plastic will eventually break with a few hard hits to the bottom.
 
Warp9 came up with a versatile and robust replacement:
 
Durable CNC aluminum plates can bend and not break with hard impacts.
Rub blocks are made with Delrin, which is long-lasting friction material.
Running a larger rear sprocket for better off-road capabilities can accommodate up to a 46 tooth (by moving the lower rub block to the forward position). It can easily accommodate the stock 525 chain and 520 conversions as well.
 
Warp9 products are MADE in the USA!
