    Thanks all you guys for establishing the facts, These little SRX 250's are little rocket ships, you have to ride one to find out, they handle awesomely, are very comfortable, and have an awesome large front disc brake, all the (I don't know where they came from) low hp ratings have probably put many a would be buyer from purchasing one. cheers again folks.

    VERY very confirming, this list confirms what I have been saying all along, but it misses out on one awesome little bike that was produced in the same era, the Suzuki NZ 250, this very lightweight DOHC 4 valve bike produced 33hp in a very light bike with the then fashionable spocked wheels.

    Well imagine how it will be with the FZR250 braking system... twin front discs and the 3WP rear is the same rear brake disc, caliper and master cylinder as the FZR... :)

    Hi All,

    NEED HELP / ADVICE

    I live in the Phillipines and own a 1984 Yamaha SRX250f. Its sat for a long time and now i'm trying to get it going again I noticed both the carb joints have perished.

    I took the carb to a dealer in the uk when I was back on a visit, he gave me the following part numbers i need ...

    51Y135860100 (JOINT, CARBURETTOR 1)
    51Y1359600 (JOINT, CARBURETTOR 2)

    He said he couldn't source any in the uk - this model never imported to uk so I wondered where I might be able to locate
    replacement parts ?

    I don't even know where they sold this model?

    HELP GUYS

    Thanks
    Paul

    SRX250 manifolds are no longer manufactured and I doubt you will find any NOS. You can use the XT250 or TT350 / XT350 manifolds as they are so close it wont make any difference. The only proviso is that the RHS manifold needs to be modified with a vacuum port if you still want to use the Standard tank Petcock.
    You can pick them up from Ali-Express as well.

    Hi Mate, I signed up to this site just so I could post this. I too owned a '86' SRX250 whilst I lived in NZ. It was my second bike and it was my first 250cc. I still have the sales brochure stored away as this bike meant everything to me at the time. The bike was quoted as 32PS. When I got the bike it had an issue with the carb and it would not rev past 6K rpm. I remember the night vividly as a 16 year old when the carb fully cleared and it revved to redline. I felt the bike had doubled in power and some kind of magic had been bestowed upon me and my machine. I ended up seizing the bike on Xmas day, hitting 160KPM with a strong tail wind and that was the start of a painful rebuild and many lessons learned for a young man of my age. The NZ bike ABSOLUTELY was listed as 32PS. I know they also made a SRV250 and the SR250 was a lot lower in horsepower. Very different machines.

    Mate, this thread is over 5 years old... but just to add to your assumptions... 32PS equals 31.5HP and 23.5kW and is the stated (supposedly) figure at the engine... in perfect conditions etc etc.
    I have the Japanese original brochure on the 1991 3WP version and it also says 32PS. Back in those days there was a lot of license to exagerate just a bit :)
    The little SRX250 was never going to be a world beater in the 250cc market but it is a great little bike..
