LONDON.- Bonhams annual sale of Collectors Motorcycles and Related Memorabilia at The Classic MotorCycle Show, Stafford on Easter Sunday, 24th April once more demonstrated the strength of the motorcycle market with a sales total of £2 million and 93% of Lots sold (85% by value). Top item in the sale was Lot 339, the 1934 Brough Superior SS100. Restored by marque specialist Dave Clark in 2004, the Brough changed hands for an on-estimate £131,300. Britains most successful over the counter racing motorcycle of all time, the Manx Norton is always in demand and the restored 1961 500cc version sold to a bidder in California for an above-estimate £29,900, reflecting its rarity as a matching-numbers example. Also British but much less well known, the 1965 DMW Typhoon 500cc twin-cylinder prototype fetched £19,550 against an estimate of £8,000 12,000. Ben Walker, Head of Bonhams Collector
