As a rule of thumb, you should try and leave a metre clear either side when passing, and to do so when the track is clear ahead. Pass cleanly and be aware of what roost behind you can do.
The responsibility is on the rider doing the passing. The rider behind needs to leave enough space to stop if the rider ahead has a problem.
You can let the rider ahead know you are there, but try not to hassle them, they are probably concentrating on their riding and will try to look for a spot to let you past.
Once ahead and clear then you can loosen the screws again.
Where's the excitement in that.
Take 2 =
1. Sus out who they are.(do they have the ability to carry out the following steps)If so don't continue,otherwise you will recieve the following yourself."not good"
2. follow them closely.
3. Make sure they know you're there.(just to make them go a bit quicker and this will get the brain activated)
4. Then back off to about 20 metres.
5. Wait for a open bit of track about 2.5 bike widths.
6. Hit the gas hard.
7. Pop the front wheel up.
8. Blast past them on the back wheel at warp factor 9.
9. Once around 5-10 metres past them drop the front wheel down.
10. Lean forward and fan the clutch.
11. Wiggle your body side to side.
12. Then look back and watch, as you fill them in with dirt and rocks.
13. Stop at the next corner and wait for their arrival.
14. Always use the excuse" Sorry mate but you were riding so slow" (everyone hates that) you came outta nowhere", ya lucky i saw ya just in time to avoid hitting you.
15. Repeat these steps on your next victim.
16. And remember "Always ride to your ability not the bloke you just passed".
It's fun to ride , but better when you roost your mates.
See you on the trails.
Ps: Make sure you have a beer or two at the end of the ride with them, this will make everything good again ready for the next time you blat past them.
