Ryan Harris is determined to take every opportunity to shine.

The Brighton motorbike racer is beginning a second season in the Superstock Cup, which forms part of the British Superbikes Series.

However, limited finances mean he cannot compete in every round, which is why he wants to make an impact every time he goes on track.

And Harris could not have asked for a better start to the season after finishing fourth in the opening round of the series at Brands Hatch.

He said: "Fourth place was an excellent start and my lap times were faster than all the people in front of me.

"I'm on a new bike this year. It's still a Suzuki GSXR1000 but it's a 2006 model.

"I'm not doing all the championship because of finance but I've got a new sponsor in multipower.co.uk and thanks to them I will be doing more races than last year and hopefully I can get on the podium."

Harris is not taking part at Thruxton this weekend but will be back in action at Silverstone in a fortnight's time.

In the National Superstock Championship, Bexhill-based team PDM Racing also clinched a fourth place thanks to their rider Scott Quigley.

He qualified on the front row of the grid and led for the first two laps but then suffered suspension problems and dropped back to fourth place.

Driver Clive Richards launches his season at Hockenheim in Germany this weekend.

The 45-year-old, from Itchingfield near Horsham, will be in action in his Caterham CSR 260 sports car in the opening rounds of the evo Caterham Eurocup.

There will be two half-hour sprint races and a one-hour endurance event and Richards will be sharing his car with Worcestershire driver Richard Hay.

Last year, as in 2005, Richards and Hay won many races together in their Caterham but missed out on the ultimate prize.

Richards said: "We have had enough of finishing second in the championship. This year it's win or bust."

Their toughest opposition includes a CSR shared by double Caterham champion Oliver Bull and 18-year-old Le Mans driver Ed Morris and another car with 2005 Eurocup Champion Jamie Constable at the wheel.

Ross Jenkins suffered mixed fortunes in the opening rounds of the Stars of Tomorrow kart series at Kimbolton in Cambridgeshire.

The 12-year-old from Woodmancote, near Henfield, had a great day in the first round on Saturday after achieving his highest ever qualifying position, fourth out of 22 drivers.

Jenkins finished fifth and sixth in the two heats which meant he started the final fifth on the grid. In a restarted race, he finished seventh, although this could be upgraded to sixth pending an appeal.

The following day was not so good. The Steyning Grammar School pupil was shunted off at the first corner and rejoined the race in last place, although he worked his way back up to 14th by the end of the first heat.

In heat two, he was pushed off twice and left with a bent stub axle which affected the handling and speed of the car. meaning he finished towards the back of the field.

From 22nd on the grid in the final, Jenkins was up to 11th when he suffered another collision which left his limping over the line in last place.

He said: "It was one good day and one poor day but out of the nine rounds I can drop four heats and two finals. Hopefully, I won't have another day like this and I will be able to drop these rounds."
