2015 World Superbike Regulations Amended

06/14/2014 @ 5:21 pm, by Jensen Beeler4 COMMENTS


For the 2015 season, the World Superbike Championship is to officially adopt the current EVO rules, in an effort to reduce costs within the premier production motorcycle racing series. Meeting this week at Catalunya though, the Superbike Commission has agreed to amend the 2015 “EVO” regulations, in order to ensure more parity amongst the variety of machines competing in the series.

As such, new stipulations regarding the 2015 World Superbike rules have been released. The new rules largely clarify what can be altered in a Superbike engine for 2015, as well as outline how OEMs can continue to develop their electronics packages (WSBK is the last World Championship to allow electronic development). For the full breakdown on rule changes, read after the jump.

Chassis Regulations:

Remain largely unchanged excepting some clarifications to several points. The tolerances applied in measuring frames have been removed.

Engine Regulations:

The previously agreed EVO regulations form the basis of the 2015 rules. However due to the very limited options available to ensure parity of performance between different motorcycles the level of tuning opportunities has been increased.

The notable points are:

  • Camshafts are free
  • Cylinder head porting is free but no welding
  • Valves, pistons and most major engine components must remain standard
  • Con-rods may be replaced with similar material but equal weight parts for safety
  • Crankcases standard
  • One set of racing gearbox ratios allowed for the whole season
  • Balancing rules no longer use weight, it will be intake restriction only

Electronic Regulations:

The FIM Superbike World Championship remains the last high level championship open to the manufacturers to develop their electronic control strategies. The manufacturers will therefore be allowed to continue to develop the electronic solutions but these systems must be available to all other teams using the same make of machine and it will be called the ‘’Superbike Kit System’’.

The notable points are:

  • Price limited Superbike Kit System available to all teams in World Superbike and other FIM championships
  • Only approved ECU’s may be used in these kits – they will be race ECU’s
  • The software of the factory team will be available to all other teams at three points during the racing season
  • The Superbike Kit System must include all of the electronic parts not fitted to the standard street machine and required for the system to be fully operational (except the wiring harness)
  • The selling price for the Superbike Kit System will be €8000
  • Alternatively the Superstock Kit ECU may be used as in the 2014 EVO regulations, this is to encourage wildcard participation

Throttle Body Regulations:

For the 2015 and 2016 season the regulations will continue to allow the addition of Ride By Wire (RBW) systems to the throttle bodies. These systems must become available to all the other teams using the same machines. They will work hand in hand with the ‘’Superbike Kit Systems’’. For the 2017 season and onwards the regulations will mandate the use of the standard throttle bodies.

The notable points are:

  • Ride by wire kits must be available to all teams in World Superbike and other FIM championships
  • Only the machine manufacturer or one appointed supplier will be allowed to provide the kit (for safety)
  • The price of the kits will be €2500
  • All non RBW machines currently utilise a solution and the control strategies are mature
  • Standard road bikes will adopt the use of this technology by 2017 meaning development continuity

Additional engine allocation SBK category:

There was an official request from a team to slightly increase the number of engines available for 2014. The Superbike Commission refused this possibility by majority.

  • Truth be told

    Give me a budget from the smallest team and i build you a twostroke that’ll smash all records including moto gp.
    And still have half the budget left to play with.

    C’mon Guy’s do some real journalism and find the truth in what is realy cost effective and discover why the track sides are empty.

    This could give some breathing space to marques other than BMW, Ducati & Kawasaki who apparently did not produce bikes which could challenged them in terms of outright horsepower, in standard road trim.

  • “Give me a budget from the smallest team and i build you a twostroke that’ll smash all records including moto gp.”

    Such delusion in an armchair pundit aside, the primary failing point of the premise is that 2-strokes don’t feature in WSBK because there are no road-going 2-strokes larger than 50 cc in pretty much any market anymore. Since the entire basis of the WSBK series is the use of production-based bikes, good luck with that whole 2-stroke thing.

    Beyond that, everybody inside the paddock is pretty much in agreement that EVO is the right direction. It won’t eliminate the factory advantages, but it will tighten up the competition throughout the grid. Since the EVO bikes are already not that far off the current factory pace, next year should prove to be a very successful recipe. I look forward to the likes of Canepa and the rest of the current EVO guys mixing it up farther up the grid.

    yeah nice joke. The 500 2 strokes of the 2000s were lapping slower than today’s WSBK bikes. The GP bikes today are 4-5 seconds a lap faster than the NSR.
