u turn for class 2b.

3 different stages in u -turns for class 2b test.

1. queuing up behind a first rider making an u turn
2. positioning to the u turn point after the first rider go off
3. making the u turn.

stage 2 is the most difficult if there is a rider before due to the short distance movement and braking you have to make without point deduction.

ground rule during u-turns:
right foot always on peg to cover brake, left foot always down. 
if your right foot leaves the right peg, immediate failure.

lets go through each step:

1. approach and queue behind first rider making u turn slowly. stop without wobble, and stop close to the left lane dotted line marking.

why? you need the distance and radius to make the next turn.

if your the first rider, good for you, skip to step 3.

2. determine your first eye aim head level and aim to the right to a certain angle so that you can make your short turning movement slowly. anchor your right foot to right peg.

open throttle and clutch out slowly to make that slow turn to the turning point.
half the distance before reaching the turning point, close throttle clutch in and foot brake gently.

as an instructor put it, front brakes should be used 1% compared to the 99% braking effort on gently stopping the bike. do not over use the front brakes since this will defintely cause wobble.

3. once you are at the turning point:

a) impt: at least 2 lanes must be clear for you to make a safe turn. if its day light you might have to stick out yr head abit and giraffe abit to watch out for vehicle to make your turning decision.

b) CHECK BLIND SPOT.

c) turn your head all the way to the right for your turning point. the more you turn your head, the sharper your turn,

d) open throttle, clutch out, drag your rear brake to control the turning.

e) complete your turn as soon as possible and also as smooth as welll, shift up to gear 2 and get out of there.

hope this helps!

wobble part 3: lane change/ blindspot check/ turning

1. when you check blind spot, do it with a gradual turn of head. dont jerk!
dont rush into a blind spot check. the more excited or last min u do the checks, the more likely you are going to cause the bike to wobble.

2. lane change should be initiated by aiming with your eyes the end point you want to reach after the lane change. lane change must be done in a straight line during class 2b test.

if you do not lane change in a straight line from start to end, and go in a 3 section line instead, (like how a lightning bolt will be drawn), definitely a higher chance of wobbling with multiple change in directions.

3. before making a turn, make sure you have completed the blind spot check in time.

you need to slow down in advance and turn in a lower gear for more power during turning e.g. gear 2 or else the bike will wobble. also, look and aim where you want to go.

4. for sharper turns from stops to avoid wobble, lean the bike in the direction you want to go, make sure you do not drag the brake (this cost points in class 2b) and look where you want to go and open throttle gradually. the power of the engine turning the rear wheel should dominate the energy of the turn, not your body steering inputs. this will reduve wobble.

5. the best way to do this gradual is to have high situation awareness and planning before committing into a change in bike direction. the less last min decisions u make in steering inputm the less wobble. the faster u go and you change direction, the more you wobble.

push starting the easy way out

i ride a phantom ta200. this means i dont have a kick starter and when your battery dies.. you gotta push start!

since phantom ta200 is an old bike no longer in production.. learning to push start isnt easy especially during class 2b lessons the cb125 was muchhhh lighter.

anyway, steps are as follows.

1. turn on the ignition, turn on the petcock.
2. change to gear 3 or 4 at least. if u find the gear lever start in neutral, roll forward a little and try again until you can change gear.
3. find a clear road of at least 10-15m to walk your bike.
4. hold in the clutch, start walking really fast.
5. when you are walking fast enough at least 10kmh or jogging pace, drop the clutch suddenly.
(not slowly release)
6. if the engine starts, clutch in immediately, and open slight throttle to keep engine going.
7. shift back to neutral!

if you do this right enough, you dont have to run! just walk fast and it will work.
if you dropped your bike and this doesnt work then you need to open wide throttle since yr engine might be flooded.
on a cold weather, especially in the rain you might have to pull the choke. i find it even more necessary if im using vpower. not too sure why for the moment.

do a push start today! dont wait till when things happen then u have to practise!
