just woundering, if iwas to buy a sports bike to fit the A2 liscense (such as sv650) but it needed restricting, how much would it effect the sound of it and the acceleration compared to origanal

The acceleration/power when restricted would depend on what machine your riding different bike cope better than others with their restriction.

This topics a fairly common one at the moment and have been many discussions about what can and cannot be ridden.

What many consider the law would follow as opposed to a random website saying it fits within the power to weight ratio and limitations;
https://www.dft.gov.uk/motorcycle-test-vehicle-list/

It's common for some websites to conflict what can and cannot be ridden as well.

A mate had his SV restricted to 47bhp (55 plate SV650, throttle stop restriction). IIRC he put a 47 tooth rear sprocket on and it pulled okay off the lights (quicker than most cars anyway). He also has a delkevic stubby end can on, sounded the same when restricted and unrestricted.

Tut Tut

You completely missed the part referring to an SV650 as a sportbike. Razz

edit: typo

The power when restricted to 35kW power would depend on what?

The incomplete list written by spergs.

Consider:
SV650S/SA = A
SV650S/SA (Restricted) = A2
GSX650F/FA = A

So, they carefully list the SV650SA, the ABS model that's never been sold in the UK. While at the same time, not listing a restricted version of the GSX650F/FA as being suitable for A2, which it clearly would be by both original power and power-to-weight.

If a bike's not on there then you might be on a sticky wicket, but it's hardly definitive nor exhaustive.

I do realise that 35kW of power is 35kW of power no matter what bike you put it on however have read people advising against the suzuki gsf bandit (again I realise it's not the same model as listed above, just an example) saying that there are better bikes on the market that would cope with the restriction fitted.

Or as an alternative could use a bike that was built for the A2 category and use all of it's power.. depends on what your after from the machine, budget etc.

Indeed, the lack of updated list of bikes that can be used for a test as opposed to what can be ridden in general confusing for new riders at the least.

Although unless in a serious investigation (fatal crash) or thorough checks by police I doubt that if stopped at the roadside for example the officer would question if the bike was restricted for A2 and had the paperwork.

Would officers glance at the full license and question the A2 entitlement or just acknowledge that the rider has a full license present.

Only reason I mentioned the above is because I debate with myself at what point (unless going for Mod 1 / Mod 2 tests with own bike) anyone would request to see a restricted certificate?

Valid although same could be said about a CBT certificate the whole some insurance companies do some don't right?

Although insurance companies don't have an option for an A2 license rather full or provisional and leaving it up to the rider to declare the modification, so I'd say it's possible to get a quote for a bike with a restriction that isn't allowed to be ridden (more than double the restriction power) without realising you have an A2 as opposed to A.

I did this with a "1994 Yamaha FZR 600" some websites say it can and some say it's has more than the original output allowed a dummy quote from MCE came back with results cheaper than I currently pay for a 125 (although I did put that I had a full license (ticked the "not yet obtained" option) with 1 years NCB.. (without that NCB the quotes soon shot up), a provisional quote to get an idea of what to save for.

35kw is about 47bhp. If all you have known is 125cc bikes then it will feel quick.

Most likely you will get used to the power in a few months but it is still not what I would call slow.

25kW is enough to give 'hot' hatches something to think about, if you catch them in in the really red part of your powerband. 35kW will get you to the legal UK limit quicker than most cars.

I'd be surprised if I use much more than 35kW on a daily basis, even when putting in overtakes.

9000bhp is doubtless lots of fun, very briefly, but might be best enjoyed on the track because racebike.

In all seriousness my "slow" 535 was quicker to the speed limit than most cars when it was on 25kW. But 25kW When I say most cars, in two years I think I only encountered an audi R8 that got away. As such 35kW is plenty for laughs on a bike that isn't too heavy.

25kW was not enough to keep up with proper bikes on a run to squires. The difference is very much what happens when opening the throttle to make a brisk overtake on an nsl road. An optimistic claim of 46bhp is better, but I'd like a bit more for assertive overtakes.

My 33BHP Bandit sounded very fast but over 6k there was nothing, no power at all, all noise (Lovely noise though... Wink ).

It was restricted with washers in the inlet rubbers.

Still enough for NSL and I kept up with IAM guys on it easy Cool
