175 Vs 125 Four Stroke

Featured Replies

Hi Guys

Spotted a 175 Scorpa yesterday and it did sound rather nice, having owned a 125 version I was wondering if the 175 (I know it's only 143cc) version is much better?

I can recall some issues with oil burners on the 175, what was wrong with them and how id they fix it?

I did like my 125 but I must admit it could have done with a bit more power, second hand 125s are going for about

as far as the differences i'm not sure but i rode the 125 and 175(143!) at birks test day up at low north and i thought the 175 had a lot more poke than the 125 and of course has all the top notch 250 model springy bits !!

Can you buy the big bore kit over the counter?

cheers in advance

The have both the 143cc and 160cc kits. They will sell you the parts, as well as do the installation if you wish. They also sell a clutch kit (different plates and discs) that makes the SY175F perform like a champ. In the review of the 175, you will note that the clutch was my main concern. After installing the B&J kit, that is no longer the case!

Cheers for the info Glenn, I did see an add for the TYS version, my 125 was a TYS version too...I found the brakes and suspension fine on that model.

As long as it's got the big bore motor I ain't too bothered about suspension spec.

arnoux, I thought the limit was 143cc, any bigger would have to have some major crank case work?

I did here of a famous pre65 rider who was doing alot of work on engine internals of the 125 version, I'll see if I can find out how he got on.
