I emailed OS to find out when they will update their site to include the specs for the R-spec and they said it will be coming soon. They also gave me these specs as the 'official' specs of the engine as tested by OS.
The 12TR R-Spec engine is being released to U.S. dealers in August. The web page for it will be online in a few days. Here are the power, rpm and other specs:
Stock Number: OSMG2007
Displacement: 0.129 cu in (2.11cc)
Bore: 0.551 in (14.0mm)
Stroke: 0.539 in (13.7mm)
Practical rpm range: 4000-38,000
Output: 1.3 ps @ 30,000 rpm
Weight: 7.7 oz (218.3g)

Looks like the max rpm will be bumped up to 38,000. Thats cool!
