Is a A2 licence Electronic Control Module (ECM) easy to remo

[Hugo Stiglitz]

Previous owner had a ECM fitted as he was on a A2 licence.

I thought ride it for a bit restricted, get used to the bike then remove.

However the bike is sluggish as I'm 102kg so it doesn't help and I'd like to remove asap.

Thing is is it a new ECU required?!

If so what does it look like (I'll get one from a breakers).

Obvious question: What bike?

Oops 2017 Suzuki SV650

Removing the ECU will mean the engine doesn't run, as it's controlling the fuel and ignition for the engine.

I did a very quick google search and found this: https://forums.sv650.org/showthread.php?t=220721

Probably an official way to do it from Suzuki (likely remap) or aftermarket way (Woolwich racing remap etc).

Following Euro 4 manufacturers had to include double redundancy in the A2 restriction, for example on triumphs they include a restricted TPS sensor and a restricted ECU, if only one is replaced or removed the bike will still be restricted. Best recommendation is to take it to Suzuki and have it removed properly.

I bought a new SV back in 08/09 at the time I was restricted, about a month or 2 after i no longer was so they swapped over the ecu and gave me the old restricted one back.
It's just a black box which plugs in, can't imagine it's hard to replace yourself

My mate’s son has got a Versys 650 which is restricted.

He’s under the assumption that it’s only the throttle stop that is restricting it and it takes 2 minutes to take that off.

It was restricted second hand. I wonder if the shop just did the easy way and just fitted the throttle stop and gave him a certificate anyway.

I must ask him next time I see him if he knows whether it’s been done properly or not.

I've got a 07 ER6-N which I've had from new, and yes that literally had a screw in stop on the throttle cable that stopped it going more than 1/2 way round.

When my restriction was off, I called the dealer to ask them to remove the restriction and they told me to just undo and remove the screw.

Electronics eh?

Back in '89 I bought an NSR 125 and the restriction was a penny washer welded into the down pipe and a lump of plastic stopping the carb slide from going all the way up

Things were a lot simpler then.

A throttle stop is as 'proprer' as any other way, assuming its a 'kit' from a company that's verified the throttle position is correctly limited to ensure correct power output - given he had a certificate this seems likely.

Much like the 33bhp days when everyone had sports bikes with a piece of paper stating they were 'restricted' ...

The double redundancy mentioned above is for manufacturers to follow, no need for that if being fitted on a pre euro 4 bike or a euro 4 bike that's not factory restricted!
