The restriction is normally done by putting restrictor plates in the inlet rubbers

aye restriction is either ecu based or done at the engine inlets.

so its still fuelled ok just doesnt get its full flow into it and starves it.


i had (well still got) a hornet 250 as my first bigger bike, put out about 38 according to specs so needed inlet restrictors (being carbed)

that red lines at 16k rpm, restriction i could only feel after 10k,
once removed (had two months till i could take em off) it catries on screaming to the limiter


id recommend getting something officially imported into the country though if you can do unless you like tracking down parts.
(hornet 250 is a grey import, can order parts but a big delay unless youve got a part book) plus servicing is a pain too, most official garages wont wanna know.
parallel imports are better but still have their downsides like headlights dipping the wrong way and can be just as expensive if not more getting to correct uk spec.

just some things to be aware of thats all.

Ah now im just confused what bike it get.

My dad has actualy offered me his Suzuki 600 (unsure what model it is - need to ask him) which i could just get restricted. Not sure if i want it tho

Woo, did my Theory this morning and passed.

Got my CBT booked for next weekend and have to sort out another 4days for the rest of the test at some point early next month

Been looking and it may actually be easier for me to get a brand new SV650 since most dealers are doing 0% finance. 1yr tax, 1yr mot, 2yr warrenty, 2yr AA cover... sort of bring its closer to the cost of getting a used bike.

The SV650 is designed for women and short men though.

Theyre grand enough, but theyre all noise and no go.

hmmm even so its something not too large for me to get started on

My first bike after the test was (I think) either a KR1-S which I still have, and one of the first of many RD350s that I still have two of. RD350 YPVSs were great (And still are - theyll cane anything up to a 600 in the real world and with a little money spent theyll cane a 600)

Most recent 2-stroke acquisition is a Suzuki RG500 which will out accelerate *any* modern superbike up to about 80/90mph. Even the standard ones were quicker accelerating than modern superbikes.

My main problem is that im going to have to restrict any bike i get (for about 10months). The SV being a V-Twin restricts well.

Im not sure how being a V-Twin aids restriction but yes, it would respond better to restriction than a two-stroke.

The restriction isnt for ten months either!

How do you figure 10 months? Its 2 years from when you pass the RAS test isnt it? Regardless of whether you hit 21 in the meantime. Unless you take the DAS course afterwards.


I keep meaning to do my own DAS - Im already on my second CBT now as the first one expired! But I never seem to be able to get the spare cash together to do it.

Well from what i understand the V-twins have more torque at lower revs and since when you restrict a bike you cant get to the higher revs it responds better.

Thats my plan, after the 10months if im feeling confident ill do my DAS

Restriction never stays in for 2 years anyway.

I thought if you hit 21... then the restriction is lifted.

nope... its either 2 years after having a restricted full licence (if your 21 or not) or when you are 21 you can do a Direct Access Course to unrestrict your licence
