The Official Mumbai Offline Meet(G2G) Thread

Rony and the rest of the Mumbai riders...a word of advice from an old fart.

1. During emergencies Front brake and rear brake together...give bias to the front brake unless it is wet, slippery or you are in the middle of a corner.

2. The bike swinging from side to side is natural because although you have stopped the front end with your weight being on it to keep it in line, the rear end is like a pendulum connected at the steering head. It is moving faster than the front end so it tries to "overtake" the front and hence the bike oscillates around the front end. If the oscillations are of reducing amplitude, you save the bike. If the amplitude is increasing - you are going to crash.

PLEASE DO NOT throw your body around trying to control the oscillations because it defies the laws of physics and will not work. Worst case you will take a safely oscillating bike into out of control oscillations by contributing to the swing by shifting your weight around.

The best move in this situation is to "feel" the bike's oscillation and you will almost instinctively shift weight forward so there is less mass on the rear wheel to amplify the oscillations (a heavier pendulum swings further...make it light!).

Slightly releasing the front brake and allowing it to move forward will also reduce the effect of the oscillations as the delta in speeds between front and rear is less severe and now that the bike has found another avenue for it's pent up energy, it will divide the force that was originally fully contributing to the oscillations between oscillations and linear forward force. This reduces the amplitude of the oscillations as well.

I don't know if you'll find this ghyaan written anywhere...this is just from experience. Anyone who has ridden a Karizma with it's awful front brakes will be aware of the rear sliding around during hard braking. I am comfortable with this phenomenon on a lighter bike but on a heavy bike like the MT-01 it freaks me out because there is more mass to control here!

quite similar when you do a rolling stoppie especially on the bikes with good front disc setup

Hey thanks for that in depth gyaan supported by physics ! ... A new insight to riding has been unleashed ... BTW by throwing the body on either sides what I meant was that I tried to counter balance the swivel ... and the bike was straight within ~2-3m ... The speed had gone down to around 10kmph due to application of front and rear brakes but the momentum was high (inertia of speed) !

A similar incident happened during my last Bhandardara-Malshej combo ride ... I was about to enter the Malshej ghat from the Otur side .... NH222 is quiet smooth & straight in this stretch .... I gained up speed upto 90kmph comfortably .... Then after few kms of steady riding suddenly I saw a bike with a pillion (and no helmets & possibly drunk) enter the road from extreme right (wrong side) ... The bike had no RVMS and rider casually rode from extreme right to extreme left at around 45 degrees or more cutting through the road .... I was coming from behind and honked heavily as I saw the bike got no RVMs .... I was planning to slip through them from left side since they were still in the opposite lane and trying to reach 1st lane on my side .... But the bike continued coming to left at a steep angle .... I kept on honking and moving further left as I had already left the 1st lane .... With hardly any time to react I kept the bike straight and maintained the speed in a view that I will pass through them safely from 2nd lane .... But my judgment had gone horribly wrong ... These guys moved further left and my bike brushed with their bike sideways with me on left and them on right ..... My right foot peg saved us from crashing into each other as it took the entire impact and broke off on the road (which I realized after analyzing the whole incident) .... Upon the impact I also applied brakes to avoid high speed crashing ... Now both the impact and the braking created a deadly swivel at around 60kmph .... My pillion (lighter than joel & of same height) was already half down on the right side with one leg on exhaust and other hanging over the seat ..... The other bike lost control almost immediately and touched ground at a very high speed ..... since they had no gears not even helmet, the wounds were severe .... My job here was to bring the lady to stop without touching the ground ... I asked my pillion to hold on and I transferred my weight on left as he was on right ... With the right foot peg gone, my right foot was on rear brake ... I pressed it gradually along with front and let the bike adjust as the road ahead was empty (thank god) ... finally the combined effort payed off and the bike came to a safe stop at around 10m from the sight of impact ... After the stop my pillion safely got down and I was thanking god that we didnt touch the ground .... I quickly got my bike parked on the left side and went back to the impact sight to see those injured bikers ..... they were stunned and still on ground .... luckily there was very less traffic that day ... I lifted their bike and put it on other side, they got up somehow with torn shirts and pants .... I could see they were a little drunk too with red eyes .... I bashed them up with strong words and asked them to get their ears checked and RVMs installed ... also to wear helmets .... still they thought it was our mistake .... I told them how can you enter the road from wrong side and then cross through all the lanes without even looking back who is coming ... Had it been a truck or bus they would have not been alive to tell the tale ... I threatened them to come to police station and get a report filed for negligent riding .... they finally accepted their mistake .... Their bike was in bad shape too .... By this time some villagers gathered at the scene and helped those guys out .... My co-riders were here and we decided to move forward after seeing the villagers attending the injured guys ... When I started my bike and took it for inspection check, I quickly realised that my right foot peg is missing .... I went back to the scene and found it on the middle of the road .... I collected it and checked the brakes and for fuel leakage ... with everything OK (as we did not hit the ground), we moved forward in search of a welder .... I knew this area since I had been there with mayur and other xBhpians as a part of my first xBhp group ride .... I took the bike to the petrol pump (which I and razor had last time visited to get his bike cleaned after the offroading to the lake jammed his bike with mud) ... We asked for a welder and luckily we were told there was one nearby .... We went there and asked the welder to get the foot peg joined back to the main frame .... But the electricity was gone and was expected by 5pm which was luckily only 10 mins away ... we waited for the electricity to come and got the peg welded .... Finally all was back to normal, but this incident left a big impact on me and I learned some important lessons from it. The most important of them was to keep cool and not get panicked ! .... The second lesson was never ever allow a pillion without RIDING GEARS ...... yes my pillion was not geared, he had only jeans, t-shirt and sports shoes to cover his body ... We had only 1 extra helmet shared between 2 pillions .... Unfortunately when the accident took place it was not my pillion's chance to wear it .... Had he fallen down on the road or worse with my bike on him, I would have to quit riding for many months or may be forever .... It was a defining moment, and I think god gave me a last chance to get my act straight ! ..... From then on I have decided, never ever take a pillion on such long rides until he is fully geared .... And with pillions not to exceed beyond 80 on highways ! .... Here again I saved the bike from touching the ground by shifting my weight counter balancing the swivel & my pillion who was hanging on right side !

I hope you guys take this narration positively and learn from it as I did ... Safety gears are a must for both rider & the pillion on any ride short/long !

PS: This is my personal experience ... The narration is based on what all I did and how at that moment ... it no where implies that its the CORRECT approach to handle such situations !

Arre rony... Thats what GS is trying to say... By trying to counter balance, you will end up increasing the pendulum effect (since you are providing it with a counter weight)... The best way is to take weight off the rear wheels (as explained by GS)...

PS: Great skills Rony

LOL ... I got that point from his explanation but im narrating the incident as is ... describing what all I did and how .. Not stating what I did was correct ... but it somehow helped me in controlling the bike from going entirely in one direction (right here since my pillion was hanging there) ... I will try to observe what GS said next time if god forbids such incident happens again ! ... And regarding skills nothing great here, some I learned by experience and some by reading xBhp threads !

Guys any update on the DIY g2g

[satyenpoojary]

Nothing, too busy with work.... havent seen NV confirm either.... so I guess time to DIY the DIY

Will have to ping Yamaha again, (just spoke with them today) but didnt mention the DIY help bit
