The brand of the 5-time world champion Danilo Rossi (on the occasion of the CIK-FIA 2022 approvals) confirms the historical models of its product range, also updating them with innovative solutions. On the other hand, the differentiation of the various chassis at a structural level is unchanged: it ranges from a "whole 30" to a "whole 32", passing through a "mixed 30-32 mm", as regards the diameter of the tubes. Let's find out in detail.

THE DR RACING KART CHASSIS

THE UPDATES

TECH SHEET

DR Racing, a brand founded by 5-time world champion Danilo Rossi, has a product range ranging from chassis for the MINI classes to those for the Junior and Senior classes, for adults. On the occasion of the 2022 approval cycle (the first following the regulatory changes made by FIA Karting in 2018, to learn more we recommend "Dossier | FIA approvals: what they are, what they are for, how long they last... the ultimate guide!") the Italian company has confirmed and renewed its models intended for kart drivers aged 11-12 and over. In a dedicated article, in the "Under examination" section, we analysed the J90 chassis, also renewed compared to the previous version. In this "First analysis", we instead relate all the news regarding the S97, M99 and M92 models (summaries for "Salbris 1997"; “Mariembourg 1999 and 1992”) which, like all chassis of the DR Racing Kart range, tell a piece of sporting history of the founder of the Italian company (to partially go into more detail, read "Dossier | The kart champions of the 80s and 90s"). These are three chassis that share a common geometry of the body, which has not however, been changed compared to the past (apart from some changes that we will highlight). How are they different? In the diameter of the tubes they are made of: the M92 is made entirely of 32 mm tubes; the M99 features 30 mm stringers and 32 mm crosspieces; finally, the S97 model has all 30 mm tubes. We had already covered them previously (read "First Analysis | DR Racing: the range is complete"), But now they are back on the market renewed. Let's see how.

The Direct Drive version of the DR Racing Kart S97 chassis.

Chassis S97 (approval number 002/CH/66), M99 (approval number 002/CH/27) and M92 (approval number 002/CH/26) are available in both Shifter and Direct Drive configurations. The new FIA Karting regulations introduced in 2018 also provide that the new approvals last indefinitely, provided that an annual fee is paid.

The different diameter of the tubes used for the construction of the bodies also affects the overall weight of the same: that of the S97 weighs about 12.7 kg, while the M99 model stands at 13 kg. The heaviest is that of the M92, which has all 32 mm tubes, with a weight of about 14 kg.
