Honda front sprocket from MX Pro - The Ultra-Life race series front sprocket is made to outlast and out-perform the competition. Precision CNC machined to exact tolerances from the finest quality hard wearing SCM420 chromoly steel that is heat treated to the maximum level of hardness possible, this insures all Ultra-Life front motorcycle sprockets will have a long-life.
Honda Ultra-Life front sprockets have been designed to increase sprocket and chain life, this is done by most front sprockets having mud cleaning grooves that are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the sprocket. Core drilling and counter profile machining insures the Honda front sprocket weight is keep to a minimum for maximum power transfer.
All Ultra-Life front motorbike sprockets are specially designed to work perfectly on all brands and types of drive chain and any brand or material of rear sprocket.

- Use a small front motorbike sprocket (countershaft) or larger rear motorbike sprocket. For every 1 sprocket tooth you change on the front, it is the equivalent to changing 3-4 teeth on the rear.
- Creates a lower gearing ratio. This is ideal for tight trail riding or tracks without many long straight sections. A lower gear ratio works well for supercross/motocross opposed to wide open riding.
For Higher Top Speed (more top end)
- Use a larger front motorcycle sprocket or smaller rear motorcycle sprocket. Again, changing the front makes a larger impact to your gearing than changing the rear.
- Creates a higher gearing ratio. Higher gearing ratios work well in high speed situations such as open space trail riding, beach riding, or mx type tracks or anywhere that doesn’t have very many tight turns.
As a general rule, for every "tooth" change on the front sprocket you’re changing the rear sprocket by approximately three to four "teeth." If you are looking for a subtle change in your gearing, add or reduce 1-2 teeth on the rear sprocket. Although gearing ratios aren't as critical to off-road riders as they are street applications, it's always nice to know where you stand. To turn the rear sprocket once, the counter shaft sprocket has to spin the number of times in the "Ratio" column. (see gear ratio image)
Sprocket gearing chart - It is very easy to work what the gearing is on your bike, just divide the number of teeth on the rear sprocket by the number of teeth on the front sprocket.
