Cobra Power SR1

THE Cobra feels reassuringly solid without being heavy. It’s well-finished, in 3mm extruded aluminium, but it will take some polishing to keep it looking smart. Sleeve options are tri-oval at £286, carbon round at £280 and aluminium oval at £264. It’s not re-buildable or re-packable, but it comes with a three year warranty. Cobra claims about a 5bhp gain, but it’s not road-legal.
