Pan American Rotax Challenge dates, format and locations finalized.
Pan American Rotax Challenge Series officials are pleased to announce that the final details on the schedule and format are set. Several adjustments have been made to the original plans including reducing the number of events from 4 to 3 for the first season. Because of a very full race calendar in the US and Canada it was decided the August date at F-1 New Jersey would not be part of the 2010
program. This long waited series will start its inaugural season in April at MSR Houston, located in Angleton, Texas 30 minutes south of Houston. This is a true international series, patterned after the very
successful Rotax Euro Challenge. Drivers from all nations are welcome to attend and future plans are for Pan American Series races to be held in Canada, Mexico and South American countries as the
program grows. Discussions for a 2011 date in Canada are already underway. The 3 events are;
*April 23-35 MSR Houston
* June 11-13 New Castle Motorsports Park (Note: the Pan American race at New Castle will take the place of the annual Rotax Summer Shootout)
* September 3-5 California Speedway
The 6 race series will crown champions at the end and award 7 spots to the 4 Rotax Grand Finals
*Junior Max – 2
* Senior Max – 2
* DD2 – 2
* DD2 Masters – 1
The three events include a Friday official practice, Saturday-Sunday format of Qualifying, Pre-Final and Final each day. One set of tires is allowed each race day for Junior and Senior classes. Mini Max and
Micro Max will use the same tires for both days. Drivers will pick up their tires each morning for races that day. Seven classes will compete at each event. The new class this year is a dedicated DD 2 Masters (415lbs). This class will also compete at the 2010 Rotax Grand Finals for the first time. Each weekend competitors will be able to earn points for finishes in the Pre-Final and Final of each day.
The top five qualifiers will also earn points each day.
The following additions are being made to the 2010 USRMC Tech Supplementary Regulations
*Technical Inspectors may use any method necessary to determine legality or Rotax Engines or components.
Section 3.0 Chassis
*Seat Mounts..All Classes – Any seat strut/stay attached to the chassis must be attached at both ends, bolts and nuts must be in a condition of compression at all times.
Section 15.1 Carburetor
* All jets must be screwed tight, this includes “inner” pilot jet. Tight defined as designed by manufacture. No Modifications
The above items will be inserted into the document prior to publishing in the official 2010 USRMC Rule Book.

INFORMATION ON CYLINDERS
Dear ROTAX customer!
We would like to inform you about following news.
New cylinder generation.
BRP-Powertrain has introduced a new cylinder generation into serial production for all
• 125 Junior MAX (part no. 223 994)
• 125 MAX (part no. 223 993) and
• 125 MAX DD2 (part no. 613 933) engines.
The specific features of the new cylinders are:
• CNC machining all around the exhaust port to minimize the tolerances of exhaust port timing.
• CNC machining of the chamfer around the exhaust port to minimize variation of appearance and to improve durability of piston and piston ring.
• CNC machining of the top edge of the central boost port to minimize the tolerance of port timing.
The CNC machining all around the exhaust port will allow the technical scrutineer to confirm the original condition of the cylinder more easily.
The new cylinders can be retrofitted to all existing ROTAX MAX engines on the market.
Sale – old type cylinders
Old type cylinders
• 125 Junior MAX (part no. 223 998)
