Good one, suitable for karizma R

Good but without company cover received. Year of manufacturing n missing details received like product info. Received only part without cover.

Not compatible with Himalayan. Don't buy this for Himalayan

Best quality

Surely the the size is correct for YAMAHA FZ25The only difference is spark gap, this plug is gapped at 0.8mm while yamaha recommend spark gap for FZ25 according to service manual is 0.65.Not problem if you have guage, just re-gap the plug to correct specs before fitting in.Engine has become smoother, the signature sound of coin rattle at 4500-6000 rpm has been considerably reduced as well.

I highly recommend to use this product as I can see there is very big difference in the pickup and running condition. Simply superb.

Using it on fz25 from last 4monts...Did Ladakh ride with it... performance is slightly better than stock plug and mileage slightly increased.. No need to change Gap because iridium required low voltage compared to other metal to produce Arc...
