UK Spec 2005 WR450

6 posts in this topic

Hi All,

Just sold my much loved CRM250 (was getting a bit old) and bought an '05 WR450 after much research.

Although the CRM was an awsome bike, the WR's power and noise does make me smile:applause: , fantastic torque and very fast - Love it.

Question:

Has anyone snipped the 'grey wire' on a UK spec bike?

Does it work on UK spec bikes?

(Sorry, I know it's a 'grey wire' question but I did search first)

BTW Just fitted a Trailtech Vapor - great bit of kit!

Thanks

James

Hello mate,

Good choice of bike :thumbsup: The UK bikes are not supposed to have the gray wire.............so as long as its not an import then you shouldn't have to touch it!

The vapor's are good, fitted one a while back myself:thumbsup:

Trev.

one thing always puzzled me was the difference in specs for the bikes. I can understand tire/tyre differences for on road registered, but for example, the following differences (from the 2007 WR):

Chassis Caster Angle - EU 27deg, US 27.3deg

Trail - EU 116mm, US 117mm

Tire (front) - EU 90/90-21, US 80/100-21

Tire (rear) - EU 130/90-18, US 110/100-18

Front suspension - different Oil capacity

Rear suspension - different fitting length

Are riding styles/conditions that different (given US spec covers US, CA & ZA, whereas EU covers Europe, AUS, NZ and Asia)?

Yes it does have a grey wire! I cut mine about a month after i bought the bike! I now seem to have more low down power. I dont notice it so much on the dirt but it definitly makes a difference when the bike is in supermotard trim!

So if the bike is on trail wheels would you not bother?

I know mine is the 02 400 and am sure its got a grey wire that aint been touched but have read that the mod is only for US versions. So confusing lol

I think it depends on your riding ability and what you want from the bike! Im not a fast dirt rider so i dont use the bikes full potential off road! however im much better on the road and road cicuits so i notice the mod more when in this enviroment! Im told that cutting the grey wire gives you a better ignition timing curve(same as the YZF) they retard the ignition slightly on the WR to make it softer and more user friendly!
