SR61N / Z3H Key for BMW Motorcycle and similar items

BMW SR61N / Z3H (also known as ILCO SR61N, Z3H, NE-6 / NE-7, NE44, N2M, B69K, or MC44) is a classic uncut motorcycle key blank widely used on older BMW motorcycles (from the 1970s through the 1990s/early 2000s), as well as many other European and Japanese bikes like Ducati, Triumph, Aprilia, Honda, Suzuki, Vespa, Kawasaki, and various mopeds. It's a simple mechanical (non-transponder/chip) key blank, typically nickel-plated steel or brass, with a slim single-sided blade profile designed for ignition, steering/fork lock, seat lock, gas cap, or other utility locks on vintage and classic motorcycles. 45 (1978?1985) R65 (1978?1988, including some up to 1986 explicitly) R80 / R80/7 / R80RT / R80G/S (1977?1987/1988) R90 / R90/6 / R90S (1973?1976) R100 series (R100/7, R100RS, R100RT, R100S, etc.) ? many from 1976?1984, and some pre-1986 models K75 (early models, 1985?1986) K100 (early models, 1984?1986) 450 / 650 variants (1984?1986 references) Pre-1984 BMW models often listed as primary fit (e.g., various Airheads like R-series up to early 1980s). 1984?1986 specifically called out for models like R45, R65, R80, K75, K100, and some 450/650. Some overlap into early 1990s Airheads (e.g., certain R100GS 1993?1997 may use similar, but many transitioned to other blanks like X59/BMW2). Always match your existing key's blade profile/length ? these are for Neiman-style locks common on vintage BMWs. Not for later chip/transponder models (post-mid-1990s). It's also cross-compatible with many other vintage bikes (Ducati fork locks, Triumph, Vespa glove boxes, Suzuki, Honda, Kawasaki mopeds, etc.), but for BMW, it's the go-to for classic Airheads.
