She concluded the event with a bronze replica and her best result, in the BikerPetition.co.uk Lightweight TT.Competing on her 39th birthday, the Northamptonshire-based racer rode in less than desirable conditions, bringing her HOL-TAJ & ESM backed Kawasaki ER6 SuperTwin, which she built at home with her boyfriend Tim McGivern, home in 28th.Maria Costello says: “I’ve had a brilliant TT, I’ve loved racing all the bikes around the most amazing road circuit in the world and I’m over the moon with my latest bronze replica, but I couldn’t have done it without my sponsors, friends and supporters, particularly my boyfriend and crew chief Tim McGivern. Thank you to you all!”The Lightweight and PokerStars Senior races were postponed from Friday due to heavy rain and further adverse weather heavily delayed the races on Saturday. The final decision saw the Senior race cancelled, with the final race, the Lightweight TT, scheduled to start at 6.35pm and run over its full distance of 3 laps.Costello took last minute advice and an update on the condition of the course from 19-times TT winner John McGuinness, who had completed a parade lap prior to the start of the final race.She had been savouring the opportunity to combine two of her passions, her SuperTwin, nicknamed the pizza race bike, and the TT course, but the weather did dampen her spirits slightly.Maria Costello says: “This race was a real highlight for me, I love racing the SuperTwin. I’ll admit that I’m not keen on racing in damp conditions and I spent the first lap working out where the damp patches were and got my head down where I knew it was dry and the Bob Jackson-tuned bike is fast. I believe it was fifth fastest through the Sulby speed trap.”Maria opted to pit for fuel at the end of lap two after spotting a dark rain cloud over the Mountain on her first circuit of the course. The rain held off and after a great pit stop she completed her final lap to take the chequered flag in 28th, collecting her 3rd TT bronze replica in the process.Costello had three different machines to compete on at the 2012 TT; a Pr1mo Bournemouth Kawasaki ZX10R, a Cookstown/BE Racing Yamaha R6 and her own Kawasaki ER6 SuperTwin.On the ZX10R she finished 37th in the six-lap Dainese Superbike race and 52nd in the four-lap Royal London 360 Superstock race. Costello took the Yamaha R6 to 46th in the first Monster Energy Supersport race, but was denied a chance to improve in the second Supersport race when an electrical fault forced her to retire at Guthries.Maria Costello says: “The Superbike race was the first time I’d ridden the ZX10 in anger and I was getting more comfortable on it with each lap and we’d been making suspension improvements each time too.“I really believe I could have gone a lot faster, so I was disappointed when they cancelled the final six lap Senior race, but I agree it was the right decision as the conditions were not safe. I’ll just have to wait until next year for the opportunity to improve my PB of 114.97mph.”Costello continued to show her support for the breast cancer awareness charity CoppaFeel! by carrying the CoppaFeel! logo on the front of each of her race bikes. She is now look forward to competing on her SuperTwin in Ireland at the Skerries and Ulster Grand Prix road races before returning to the Isle of Man for the Manx Grand Prix in August, when she will compete on classic machinery from Bob Jackson and Team Classic Suzuki.
