Easy to manoeuvre, simple to use and featuring an electric starter and enclosed drive chain, the Yamaha SR125 is an ideal machine for new riders and commuters. Driven by a highly reliable 125 cc 4-stroke engine that produces a smooth band of power, this economical motorcycle is one of the most rider friendly bikes in the class. Natural riding position, slightly raised handlebars and pillion grab rail make for high levels of comfort for you and your passenger, while the low seat height and compact dimensions ensure lightweight handling around town.Which is nice, but it didn't stop me nearly wheeling when I came to my first roundabout. It didn't take me long to get used to riding a bike, and now I think it's a lot more fun than driving a car any day! (except a day that's cold and wet, perhaps) I have had a few problems, mind you... most of which are down to the fact that I bought my bike from Motorcycle City.
When I have ordered replacement parts, they have taken ages. they once took 2 months to get a replacement clutch lever, and when it came, it was the wrong size! just a couple of days later I ordered and got the part from a smaller local bike shop!
I have had a few accidents, bt none that were really my fault! The first
time it rained after I got my bike, I slipped on a man-hole cover, and
slid along for a bit. no damage was done, but I lost the battery cover.
A while later I was riding to uni, when I missed my turning, so I did a
U-turn and then went to turn into the turning I missed (clear?) but a car
drove straight into the side of me. I got knocked off my bike and landed
running down the road. The clutch lever snapped off (I've now got the end
as a funky key-ring) and my bike went into shock and wouldn't start. The
driver of the car said she'd thought I was just doing a U-turn, and wasn't
expecting me to carry on round the corner. I'm not sure who was wrong.
It was only £5 for the lever, so I'm not bothered (and key-rings
can cost a lot more than that!) Later still as I drove to work, it was
raining and I slipped going round a corner on Farnborough airfield at 5
mph. I was right outside the fire station, and apparently they'd had a
spillage. Apparently diesel is slippery! No damage done, but I was shocked
to slide so far, so slowly.
The worst accident
I've had is in Alderbury. I decided to come home for the day from uni,
because a friend had annoyed me by changing her plans and not coming out
with me for the day, so I wasn't really in a good mood any way, and then
I got to Salisbury, and Matt & Tiggy's was closed (Used to be a great
little cafe, now smells of fish). That was the final straw, so I stormed
off home in a huff, and when I came to alderbury, I crashed into a barrier
on the Alderbury turning, and caused £100 of damage. Whoops! As you
can see from the picture I have cunningly repaired the speedo with insulation
tape. I will get a new one when money permits.
Other that that I've had to replace the speedo cable when the old one
snapped after my accident (that was done by Motorcycle City under warrantee,
gullible!) I also had to replace both hand levers and the gear change lever
because my bike kept getting blown over in the wind whilst at university.
It's perfectly happy now in it's garden home...
rip
Sadly on 17th November 1999, my Yamaha SR125 passed to the other side.
Greatly assisted by me driving it under a lorry, it has to be said. What
happened was this: I was on my way to work at 8.40am, overtaking the rush
hour traffic as I normally do. So the lorry going about 20mph in front
of me didn't pose any threat, especially since there was so much room avalisble
to the prospective motorcycle overtaker. Unfortunately by the time I got
down to the cab end of the lorry there was not so much room, and somehow
I managed to catch my handlebar on the side of the lorry, and get all tangled
resulting in a bike flipping over and over with me being dragged along.
luckily my bike went into the lorry and not me. Not luckily it will cost
£1,485 to repair the bike. It cost £1,800 new! So farewell,
then, Yamaha SR125
