BSB 2020

The 2020 BSB series finished with exciting racing at Brands Hatch, with relatively good conditions for the time of the year.  Jack Scott #55 on the JJ Racing Harris GP2 bike went into the last race of the championship with a very slim lead, unfortunately after leading for the first half of the GP2 class race, he was overtaken by the eventual series winner and crashed chasing him down in an effort to regain the lead in both the race and the championship. Disappointing, but it in no way diluted the impressive season that Jack and his tireless team have had, the presentation in the paddock and the performance on the track has been an absolute credit to them.

Donington Park, BSB GP2 Class October 2nd/3rd 2020.

Jack Scott, J J Racing, Harris GP2

Donington Park, BSB GP2 Class October 2nd/3rd.

After a heavy crash in appalling conditions on Saturday the team worked tirelessly to rebuild the bike for Race1, whilst the chassis was now in good order for the race there was an intermittent misfire. Jack dug deep and completed the race with the bike not performing up to its usual high standard, although 2 laps adrift at the end of the race it did ensure that Jack got important points toward the Championship standings. After the race, the team further investigated the cause of the misfire and it was found that damage had been done in the Saturday crash to the wiring loom, causing an electrical fault, hence the misfire. This was rectified and with no Sunday practice, Jack entered the race hoping that the electric repair had fixed the problem and that the chassis set up the team elected was suitable. Starting from 26th on the grid Jack had tremendous opening laps with the bike running well, over the course of the race Jack passed other GP2 and Supersport riders to finish 10th overall and 2nd in the GP2 class. This superb ride gained him the points he deserved, and at the end of the weekend, Jack still led the Championship by 8 points, all to go for at the final round of the Championship at Brands Hatch.

If you are considering racing the GP2 class or building a GP2 track day special, please do not hesitate to contact Harris Performance to discuss the options they offer for their Yamaha R6 powered GP2 bike.

Harris GP2

The latest Harris GP2 chassis is the culmination of over 40 years of Harris designing, developing and building race chassis, and preparing race bikes for all classes of road and closed circuit racing from Club through to Grand Prix and World Superbike.

Whilst some aspects of the latest GP2 chassis are a derivative of our previous Moto2 chassis, the 2020 bike offered is a new concept, using a combination of new and established design and fabrication features. The brief was to build a chassis that is aesthetically current, performed well, but also with the race technician in mind, accessible and easy to work on.

This chassis has been designed to give full adjustability, and has been built light enough to be competitive but strong enough to be rebuilt in the event of an episode.

Materials use in the construction are all aircraft specification, the trellis aspect of the frame is T45 high tensile steel tube, with fully mitred joints, Manganese bronze welded to ensure strength with the required flex without compromising joint integrity. The CNC machined structural parts, brackets and fittings are aluminium, all fasteners are Gr5 Titanium, apart from the special High Tensile dowel pin arrangement adopted for the frame assembly.

The aluminium parts are supplied surface finish as machined/fabricated, whilst the tubular T45 structure is supplied bare or painted to customer requirement.

The oval head stock gives provision for multi fore and aft adjustment without taking up valuable space around the headstock area, various offset inserts are available to give different rake and trail adjustment to the front fork assembly.

The swing arm pivot, rear suspension linkage, flex characteristic of the swing arm and the wheel base of the chassis are all adjustable. Optimum set up from circuit to circuit is attainable.

The relationship between Yamaha and Harris goes back decades, Harris were one of only 2 chassis manufacturers worldwide to be given licence by Yamaha Motor Company, Japan, to develop, build and sell customer bikes using the legendary YZR500 engine for Grand Prix, with engines , spares and ancillaries supplied for the Harris chassis direct from YMC, Japan. Because of our history, and the strong performance and reputation of the Yamaha R6, and as so many race teams currently use and are conversant with the Yamaha engine and ancillaries, and have experience with the Yamaha and established spares inventory, Harris elected to use this power unit for the current bike.

The chassis is now developed and Harris look forward to supplying customer chassis for BSB and other “open” class racing. The bodywork fitted to the bike during testing has been temporary, Harris have been working with aerodynamicists to develop 2020 bodywork, this has been done taking into account current GP trends and styling and aerodynamic slip.

The Harris GP2 R6 development bike has been equipped with established high-end bolt on chassis component parts, Brembo brakes, Ohlins suspension, PVM lightweight aluminium wheels, YEC kit ECU and wiring loom, AIM dash and data collection, HEL brake plumbing, Super B battery, Harris multi adjustable yokes and Ti fasteners. However, we offer flexibility, we are happy to discuss any specification to suit customer requirement, from what we consider to be a basic frame kit: – Frame, swing arm, aluminium fuel cell and for the customer to use donor components to complete the build, through to a full on rolling chassis, or anything between. All parts are available individually, and going forward will be available from stock.

If building a GP2 race bike is part of your race plan now or in the future, please don’t hesitate to contact us to discuss your project and the product and service we offer.

Team Force won the 1st Round of the European Endurance Classic Championship.

A victory at Le Castellet during the weekend of 10-12 May for the Team Force team. Such a lot of work has been put into this, so well done to all involved.

Riders Gian and Bruno rode the Harris F1 Suzuki during the Endurance Classic race and their strategy paid off. Behind the scenes the mechanics Alain, Italo and Jean-Jacques worked hard supporting the team managed by Christian Hames.

We hope this hard work also pays off at the next round at the Championship in Oschersleben.

The Royal Enfield 650 Twin

World record (to be confirmed by FIM) for Royal Enfield.

A drag sprint bike instigated by the Special Projects Team at the Bruntingthorpe, Royal Enfield Technical Centre recently captured a land speed record of approaching 160mph at the Bonneville Salt Flats.

A production Royal Enfield 650cc twin engine prepared for the attempt by American master tuners S&S, housed in a chassis designed, developed and built by Harris Performance (a unit of Eicher Motors Ltd) and ridden by Cayla Rivas culminated in the World Land Speed record.

Conditions and “the salt” were perfect for the attempt, the S&S Royal Enfield engine ran like a dream, the chassis was stable and Cayla was on her game, the combination was a well-deserved world record.

Custom Drag Bike

European drag race bike

In addition to the production development work we undertake for Royal Enfield, we also get involved in some very surprising concept bikes.

The drag bike shown here with Alan Cathcart aboard is a good example.

The design brief was to build a custom/show bike, using the new twin engine, that could also acquit itself well in a couple of European drag races. Mission accomplished we think.
