Tell us what you think of this 125 SR 1983

presentation of the 125 SR 1983

an economical custom par excellence, the SR is not a show-off, but rather a utilitarian with a touch of charisma. The SR's urban-friendly design is powered by a solid, slightly vibrating but reliable 4-stroke single, delivering decent performance for city use. Once out of town, the mono runs out of steam at around 90 km/h - optimism and patience are required to gain a little more speed. A bit of a headwind, however, and the mechanics give nothing away above 80 kph. Simple in design, the machine offers decent dynamic performance and comfort features such as an electric starter, a low seat height and a protective chain guard (clothes-wearers will appreciate this). A competitor to the Suzuki GN, it is nevertheless more expensive than the latter.

Hi, can you tell me where I can find a replacement bulb for the headlight of a 1997 Yamaha SR? The bulb base is special because 3 "POINTS" are used to fix the bulb on its support.

thanks in advance if you have any tips. :-) 03/20/2024 14:12 Rating : 5/5 Respond to NICO

i have the same question as you about the fuel type of the Yamaha sr 4 did you find the answer?
si oui super merci de me répondre 09/11/2016 09:07 Rating : 3/5 Participate in the conversation

Romain Sibot

Hello, the answer is a little late but according to Yamaha none of their models are E10 compatible. And generally speaking, it's best to avoid using it on motorcycles, as it's bad for the rubber (hoses, seals...etc) and also the reservoir, among other things. The few cents you save at the pump may be lost a few years down the line. 10/17/2016 12:20 Rating : 5/5 Participate in the conversation

Is it a problem with the coil under the tank, or the electronic box under the seat, or the electronic transistor box on the left side of the bike?

Bonne machine

Cathare Model 1981

Economical to buy (-1,000 euros) and to use (2.5 l to 3.5 l, with minimum maintenance), it will go a long way (50,000 km).
A bubble greatly enhances comfort, enabling you to ride up to 200 km in a day without getting too tired.
Good suspension with a passenger. Average handling, decent braking. Smooth, easy-to-handle controls. Attracts no covetousness! Parts readily available. 09/26/2013 13:58 Rating : 5/5 Respond to Cathare
