    6.2 Engine??

    Hi all.
    Quick question. Does anyone know if a BMW Motorrad SBK 6.2 motor is a generation 2 or 3 engine?
    Cheers

    I thought it was based on the gen 3 engine.

    I think 5.x would be the Gen2, so Gen3 would be 6.x

    Update: that was utter nonsense

    6.2 can be done to any gen 2+3 engine (i have 2 of them ).

    95% of the work is in the head,crank,pistons+rods are all standard,but rods+pistons are matched for balance.Ti valves,springs,billet inlet+exhaust cams.no porting though suprisingly.makes around 215-220 depending on dyno,but have much better mid range i find.
    then the variable airbox inlets are modified,and also have a heavier weight (assume to drop them back faster,but not 100% sure of the reasoning?).

    £12k from Alpha!!!

    if your interested i'm splitting my spare alpha engine+Nova LITA gearbox,the head is basically a bolt on part..

    BMW Race Engines

    5.2 - Superstock
    6.2 - BSB/SBK
    7.2 - WSBK

    The last time I spoke to BMW they said the ‘guide’ prices for race engines was ~€10,000 (5.2), ~€17,000 (6.2) and ~€23,000 (7.2). The BMW Race Dept can also build engines to suit specific championships. Generally the higher the level of racing, the higher the cost!
