Speed Tuned 19XZ-B ABC
Finesse and fuel economy for tight, twisty 1/8 scale tracks!
Ever wanted one or two less pit stops during a main to extend your lead over your competitor? The O.S. 19XZ-B Speed offers 10% better fuel economy over the current 21XZ-B Speed with the 21J2 carburetor and 6mm carburetor reducer and still has all the performance you need to win.
The 19XZ-B Speed also incorporates a DLC (Diamond Like Carbon) coating crankshaft to reduce friction and improve wear life and durability and also prevent corrosion. The crankshafts passageway is silicone filled to direct the air smoothly into the tuned cylinder assembly and crankcase.
- The ceramic bearings reduce rolling resistance throughout the power performance.
- A square bore/stroke (1:1) short stroke provides stress free performance and sharp acceleration.
- The ultra light weight cylinder head is smaller and weighs 8 grams less than the current 21XZ-B Speed head; overall weight is 12 less.
- The black anodized crankcase with fins helps direct air flow over crucial parts of the engine and helps dissipate heat to keep it cooler.
