Be advised, pure aluminum is too soft for modern engine cases but it does not corrode. Alloy is very strong and light but corrodes like crazy. That's why they get painted.

Thanks, everything you said makes sense. If anyone knows what year they switched from silver to black I'd appreciate that info.

The silver cases were not a good finish, Triumph used a paint that was was porous and would stain very easily with no way of removing the stains.

Thanks for that info. I like your websit also.

My 07 Thrux has the silver powder coat cases. TBh they are a bugger to keep clean. The Black is easier to look after. I believe they changed over here in 08 to Black.

Crankcase colour change from silver to black:-

Bonneville - Model Year 2007 on.

Thruxton - Model Year 2007 on.

Scrambler - Model Year 2007 on

T100 - Model Year 2009 on.

Note. Black crankcases were first introduced as an option on Jet Black Bonneville's only in 2004.

It must vary by country - in the UK the T100 engine cases are still chrome by default - the T100 Black SE has black cases but not all models.

My 2005 has clear-coated "natural" engine cases.

My silver 2001 cases and chrome covers are pretty near perfect with nearly 55,000 miles on the clock. The bike has always been washed with heavily diluted Castrol Super Clean and shined with with TW Ice Products.The only surfaces on my bike that have dulled are the frame and the black cylinders. Any thoughts on how to brighten these?

People appear to be confusing engine covers (Clutch, alternator & sprocket) with the actual crankcases here. The info I gave above relates to the actual crankcases not the engine covers.
