I’ve got the same problem after only 100 miles Luckily I was at work when it happened and I’ve had to leave my bike there spoke to my dealer and they had seen this post about the quick fix with the bridge but they told me that they cannot tell me to do the quick fix as it would void the warranty so no bike until it goes back to the dealer so I will have to hir a van and pay somebody to drive it back has my Nearest dealer is 100 mile away And in the meanwhile I’ve had to go back to having taxis to work and back so this little problem is going to cost me a fortune not very happy this is a real shame as I was really enjoying This fantastic little bike 

It is always your decision if you fix your bike. Bridge I explained can be done for a time needed and removed delivering to service later. 

In fact - sensor works just as a bridge. Opens or closes circut. There is nothing one can damage bridging this 2 pins. But as I said - it is up to one in need. ;-]

Update: my dealer was very good, he had Super Soco replace the sensor under warranty, but it took many days and many contacts. With the new sensor I turned for about 50km and then broke again. I didn't have the courage to make the dealer waste any more time, I put the jumper back on and now I ride like this.

Update the other night spoke to someone on super soco uk Facebook page Who was very helpful and agreed it was my parking stand sensor that needed replacing and I told him that it was a bit of hassle take back to the dealer which is quite a distance and if it was possible that I could purchase one and fit it myself as it looks quite simple and He gave me the email address for the Super soco UK warranty And to send them a picture of the bike with the stand down and showing The display not in park to prove the problem And to my surprise the next day I got a nice email from SUPER SOCO UK advising that they had sent me a replacement Which I received the following day it was a bit of a pain to fit because the screw holding it on was so tight it rounded the screw off so had to use a pair of grips to get it off but after that fitting the new one was simple overall I could not fault the great service Well done SUPER SOCO 10 out of 10 And they also told me that they had identified a faulty batch which had been destroyed and there should be no problem with the new one fingers crossed

There's also the possible fault of the red triangle button at the throttle side, right side that can be a little bit jiggly. If it causes other effects as well as error 98 is to be seen but if that was the error all along I will be very happy.
